So am I. What does pthread_mutex_unlock return when failing? According 
to POSIX it should be one of these:

The pthread_mutex_lock(), pthread_mutex_trylock(), and 
pthread_mutex_unlock() functions may fail if:

[EINVAL]
     The value specified by mutex does not refer to an initialized mutex 
object.

[EAGAIN]
     [XSI] [Option Start] The mutex could not be acquired because the 
maximum number of recursive locks for mutex has been exceeded. [Option End]

The pthread_mutex_unlock() function may fail if:

[EPERM]
     The current thread does not own the mutex.

These functions shall not return an error code of [EINTR]

Best,

Ion
