Um, so what do you do when some library (say like Kerberos) wants to
use pthreads under the covers?  Does that work, or does lwp and
pthreads have overlapping namespaces?

And what do you do on Solaris 10, where pthreads has been merged into
libc and effectively all programs (a) must be compiled dynamically,
and (b) are effectively always linking with -lpthread?
