Since work_push can block on a condition, the core thread is at risk for being blocked by the HTTP processing. It might be better for the core-thread to schedule this callback as a general-work item so it runs on an I/O thread. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
