I would like to commit this module to trunk. It's a watchdog module that creates a worker threads either in parent, child via an API, and it's not for standalone use, but for other module usage like mod_heartbeat, probably mod_jk and others that need maintenance threads.The reason is because couple of modules would benefit from this functionality, and this adds a common API. Usage is very simple 1. ap_watchdog_get_instance 2. set singleton mode (only one child will execute) 3. register a callback(s) with desired interval Module can either use pre-created watchdog instance or create it's own in special cases thus creating additional thread(s) For example heartbeat would be by an order of magnitude simpler (I took some concepts from it) Also I'd love to register the callbacks for balancer so transferred method can normalize the load. Comments?
A huge +1.The availability of this API will help mod_cache and friends to keep the cache cleaned without expecting the admin to jump through hoops, and mod_session_dbd needs this to clean up expired sessions from time to time.
