Tweak code a bit to be POSIX compatible, when a cancellation request
is acted upon, or when a thread calls pthread_exit(), the thread first
disables cancellation by setting its cancelability state to
PTHREAD_CANCEL_DISABLE and its cancelability type to
PTHREAD_CANCEL_DEFERRED. The cancelability state remains set to
PTHREAD_CANCEL_DISABLE until the thread has terminated.
It has no effect if a cancellation cleanup handler or thread-specific
data destructor routine changes the cancelability state to
PTHREAD_CANCEL_ENABLE.
