Well, just get it working under FreeBSD with native threading
(KSE) and modify the port to respect PTHREAD_LIBS instead of
linuxthreads.  Others can help you test on SMP, but in theory
it should behave no differently than on UP.  You can simulate
KSE/SMP on a UP system by setting the following sysctls:

	kern.threads.debug: 0 -> 1
	kern.threads.virtual_cpu: 1 -> 2

Let us know if you have any problems.
