Description

Our thread monitor does a good job of telling us about stuck threads. If a thread is stuck trying to synchronize on an object the monitor even tells us the name of that thread. We should enhance this to give us a stack dump of the thread that owns the lock. Sometimes this is a thread that's not monitored by ThreadMonitor so we don't know what it's doing unless someone takes a thread dump of the whole process.
