	I don't agree.  Do test, run by again, do test.

	I read a discussion about libpthread vs libthr, so I tested on
	my environments(7-current SMP and 6-stable UP).  My result is
	NOT YET, and I resurrected to libpthread environment.

	1. libthr is not enough mature.
	   At this time, libpthread's pthread API support > libthr's
	   pthread API support.  So libthr lacks of compatibility with
	   libpthread.  It is not good.

	2. Not PTHREAD_CFLAGS/PTHREAD_LIBS clean
	   At this time, tinderbox doesn't test PTHREAD_CFLAGS/
	   PTHREAD_LIBS clean.  We have need to check PTHREAD_CFLAGS/
	   PTHREAD_LIBS clean on all ports.

	3. Is libthr environments useful?
	   I don't think.  Yes, I think that some applications like mysql
	   are useful.  However, in all FreeBSD environment system, by 1
	   and 2, libthr is not useful.
