Yeah, I suppose.  We already do record locking of all the fixed
spinlocks (BufMgrLock etc), it's just the per-buffer spinlocks that
are missing from that (and CRIT_SECTION calls).  Would it be reasonable
to assume that only one buffer spinlock could be held at a time?

I agree.  Anyone object to changing pg_ctl to do -w by default?
What should we call the switch to tell it to not wait?  -n?
