New Revision: 4892
URL: http://trac.nginx.org/nginx/changeset/4892/nginx

Log:
ngx_http_keepalive_handler() is now trying to not keep c->buffer's memory for
idle connections.

This behaviour is consistent with the ngx_http_set_keepalive() function and it
should decrease memory usage in some cases (especially if epoll/rtsig is used).
