* Makefile.am, configure.ac: Add psxspin02 to exercise case where
	trylock is unable to obtain the spinlock and that attempting to
	unlock a spinlock from a thread which did not lock it works as
	expected.
	* psxspin02/.cvsignore, psxspin02/Makefile.am, psxspin02/main.c,
	psxspin02/psxspin02.doc, psxspin02/psxspin02.scn, psxspin02/test.c:
	New files.
