+Gzip Gunzip: always flush busy bufs when the incoming chain is NULL.
+
+After the system send buffer is full, NULL incoming chains are used to
+flush pending output upon new write events. The current gzip and gunzip
+filters may intercept NULL chains and keep the data stalling in
+nginx's own send buffers, leading to request hanging (until send
+timeout).
+
+This regression had appeared in nginx 1.7.7.
