NetBSD on a Pentium (i386 port) so yes, it does have TAS.  I assume you were 
thinking about the spinlock emulation.

I have been looking through backend/storage/lmgr/lwlock.c and 
backend/storage/lmgr/spin.c myself and can't find any place that it can get 
into an infinite loop without making a system call within the loop.  It's 
very odd.  Also odd, why would running over NFS have any bearing on it if we 
could find such a place?
