Excellent. I think there's a bug in your timed_lock --- it doesn't quit when the timeout expires. Easy to fix --- just check the return value from m_cond.timed_wait.
t0: thread A holds the lock t1: thread B calls lock() and does internal try_lock() twice (both fail) t2: thread A calls unlock() and does notify_all() (nobody's waiting) t3: thread B enters wait() on condvar and waits and waits and waits...
OK, these are both fixed and checked in to my SVN: http://www.neuromancy.net/fisheye/browse/mantra/trunk/Mantra-I/mantra/utils/... The timed lock issue was silliness on my part. My original implementation using the old threading interface did not have this bug, but I rushed trying to convert it from the old interface to the new, and since I don't use timed_lock that much, did not test it. My bad. PreZ :)
