/* Testing the platform for POSIX threads. This is not meant */
/* to be an exhaustive test at this point but more a sanity check */
/* that PACE works (at least somewhat) as advertised. */
/* This program simply creates some threads, joins them, and then */
/* exits. */
/* */
/* This test is largely taken from the O'Reilly _Pthreads */
/* Programming_ book and accompanying example code. */
