"identifies a thread" well enough for what?  pthread_t is suppose
to be opaque.  Whether it is an int, pointer, or whatever, it is
implementation-defined and not suppose provide any more information
than available through the standard pthread interfaces.  There are
some non-portable interfaces in <pthread_np.h> though.
