In boost 1.35 and 1.36 the implementation of mutex::timed_lock() and recursive_mutex::timed_lock() for posix-platforms with BOOST_PTHREAD_HAS_TIMEDLOCK defined looks like this:
bool timed_lock(system_time const & abs_time) { struct timespec const timeout=detail::get_timespec(abs_time); int const res=pthread_mutex_timedlock(&m,&timeout); BOOST_ASSERT(!res || res==EBUSY); return !res; } The assertion following pthread_mutex_timedlock() always fails in case of a timeout since the system call returns ETIMEDOUT when timed out and not EBUSY (according to the open group specification http://www.opengroup.org/onlinepubs/009695399/functions/pthread_mutex_timedl...)
You're not the only person who's spotted this. I'll open a trac ticket, and fix it when I'm next using my linux box.
