* src/mqueue.cxx: Fix problem with mq_timedsend() and mq_timedreceive() timing out with zero timeouts even when there is room in the queue. * src/pthread.cxx (pthread_exit): Added code to disable cancellation requests during thread exit. This allows thread cleanup handlers to issue system calls when cleaning up thread resources.
