Thanx, will try.

The problem I'm experiencing, however, is that it goes into what looks
like spinlock states
on the mutexes (something like all the threads on the mutex(es) etc.
wake up all at once, then spins on the locks after some thread grabbed
the lock) This then grabs both CPUs by asterisk, and the system is
unresponsive, and usually by the time I can execute a command like
that, the system have already recovered :(
