this is more of an SMP issue than anything else. If a compiler gets
"cute" and moves things around, it can suddenly expose a timing hole that
is not obvious because the source doesn't show it. IE moving the
instruction that "clears" a lock back a few instructions normally wouldn't
hurt, except that it will kill us on a real SMP machine...
