Log message:
Promote __mp_lock_spinout to long
This lets us implement larger MP_LOCKDEBUG thresholds on very fast
machines, so that we can tell transient contentions apart from actual
lockups. deraadt@ expressed concerns that bumping the threshold might
hide actual problems, but this diff doesn't change the threshold. As
mentioned by mpi@ and claudio@ MP_LOCKDEBUG is a very crude tool, but
it's the only tool we have right now.
ok miod@ claudio@
