When doing the locking in C++, we should really make stacklock volatile.
That affects especially the unlock and locked methods, where you'll
never know how gcc optimizes away.

spinning should be volatile as well, but it's up to you if you already
add that, or if we only do this when we add the SIGKILL patches.
