+Gzip filter: handle empty flush buffers.
+
+Empty flush buffers are legitimate and may happen e.g. due to $r->flush()
+calls in embedded perl.  If there are no data buffered in zlib deflate()
+will return Z_BUF_ERROR (i.e. no progress possible) without adding anything
+to output.  Don't treat Z_BUF_ERROR as fatal and correctly send empty flush
+buffer if we have no data in output at all.
+
+See this thread for details:

+Core: protect from subrequest loops.
+
+Without protection subrequest loop results in r->count overflow and
+SIGSEGV.  Protection was broken in 0.7.25.
+
+Note that this also limits number of parallel subrequests.  This
+wasn't exactly the case before 0.7.25 as local subrequests were
+completed directly.

+Gzip filter: handle empty flush buffers.
+
+Empty flush buffers are legitimate and may happen e.g. due to $r->flush()
+calls in embedded perl.  If there are no data buffered in zlib deflate()
+will return Z_BUF_ERROR (i.e. no progress possible) without adding anything
+to output.  Don't treat Z_BUF_ERROR as fatal and correctly send empty flush
+buffer if we have no data in output at all.
+
+See this thread for details:

+Core: protect from subrequest loops.
+
+Without protection subrequest loop results in r->count overflow and
+SIGSEGV.  Protection was broken in 0.7.25.
+
+Note that this also limits number of parallel subrequests.  This
+wasn't exactly the case before 0.7.25 as local subrequests were
+completed directly.

+Gzip filter: handle empty flush buffers.
+
+Empty flush buffers are legitimate and may happen e.g. due to $r->flush()
+calls in embedded perl.  If there are no data buffered in zlib deflate()
+will return Z_BUF_ERROR (i.e. no progress possible) without adding anything
+to output.  Don't treat Z_BUF_ERROR as fatal and correctly send empty flush
+buffer if we have no data in output at all.
+
+See this thread for details:

+Core: protect from subrequest loops.

+Without protection subrequest loop results in r->count overflow and
+SIGSEGV.  Protection was broken in 0.7.25.
+
+Note that this also limits number of parallel subrequests.  This
+wasn't exactly the case before 0.7.25 as local subrequests were

+Gzip filter: handle empty flush buffers.
+
+Empty flush buffers are legitimate and may happen e.g. due to $r->flush()
+calls in embedded perl.  If there are no data buffered in zlib deflate()
+will return Z_BUF_ERROR (i.e. no progress possible) without adding anything
+to output.  Don't treat Z_BUF_ERROR as fatal and correctly send empty flush
+buffer if we have no data in output at all.

+Core: protect from subrequest loops.
+
+Without protection subrequest loop results in r->count overflow and
+SIGSEGV.  Protection was broken in 0.7.25.
+
+Note that this also limits number of parallel subrequests.  This
+wasn't exactly the case before 0.7.25 as local subrequests were
+completed directly.

+Gzip filter: handle empty flush buffers.
+
+Empty flush buffers are legitimate and may happen e.g. due to $r->flush()
+calls in embedded perl.  If there are no data buffered in zlib deflate()
+will return Z_BUF_ERROR (i.e. no progress possible) without adding anything
+to output.  Don't treat Z_BUF_ERROR as fatal and correctly send empty flush
+buffer if we have no data in output at all.
+
+See this thread for details:

+Core: protect from subrequest loops.
+
+Without protection subrequest loop results in r->count overflow and
+SIGSEGV.  Protection was broken in 0.7.25.
+
+Note that this also limits number of parallel subrequests.  This
+wasn't exactly the case before 0.7.25 as local subrequests were
+completed directly.

+Gzip filter: handle empty flush buffers.
+
+Empty flush buffers are legitimate and may happen e.g. due to $r->flush()
+calls in embedded perl.  If there are no data buffered in zlib deflate()
+will return Z_BUF_ERROR (i.e. no progress possible) without adding anything
+to output.  Don't treat Z_BUF_ERROR as fatal and correctly send empty flush
+buffer if we have no data in output at all.
+
+See this thread for details:
+http://mailman.nginx.org/pipermail/nginx/2010-November/023693.html

+Core: protect from subrequest loops.
+
+Without protection subrequest loop results in r->count overflow and
+SIGSEGV.  Protection was broken in 0.7.25.
+
+Note that this also limits number of parallel subrequests.  This
+wasn't exactly the case before 0.7.25 as local subrequests were
+completed directly.
+
+See here for details:

+Gzip filter: handle empty flush buffers.
+
+Empty flush buffers are legitimate and may happen e.g. due to $r->flush()
+calls in embedded perl.  If there are no data buffered in zlib deflate()
+will return Z_BUF_ERROR (i.e. no progress possible) without adding anything
+to output.  Don't treat Z_BUF_ERROR as fatal and correctly send empty flush
+buffer if we have no data in output at all.
+

+Core: protect from subrequest loops.
+
+Without protection subrequest loop results in r->count overflow and
+SIGSEGV.  Protection was broken in 0.7.25.
+
+Note that this also limits number of parallel subrequests.  This
+wasn't exactly the case before 0.7.25 as local subrequests were
+completed directly.
+
+See here for details:
