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?
