Strange pthreads problem

Hi,
        I'm running RedHat glibc 2.2.5-42 on a Celeron processor and am having
a strange problem in one of the programs I'm running (the Mono
debugger). It seems that a thread of the program is blocking in a call
to pthread_mutex_unlock(). Does anyone have any idea what could be
causing this? The debugger admittedly is going through about three
levels of synchronization abstractions, but it's definitely spinning
inside __pthread_unlock(). I peeked at the code but don't have any
experience with pthread internals, so any wisdom would be much
appreciated.

        Thanks in advance,
                Peter
