 > Well, it doesn't fail randomly.  Most of the possible failures either
 cannot happen with boost::mutex or are a result of undefined behavior.
 However, EAGAIN and ENOMEM appear to be possible.
 On QNX pthread_mutex_lock may also return EDEADLK - if mutex was not set
 as recursive, or ETIMEDOUT if "A kernel timeout unblocked the call", and
 all this return values including EAGAIN are possible. At least this errors
 should be logged somewhere and execution of the thread should be
 cancelled.
