Ian, as you noted earlier, on an MP machine getting reliable replay
will be difficult - locks need to be acquired in the same order during
the replay as they were acquired initially. In my previous life we had
toyed with implementing a similar strategy on a microkernel (Chorous)
based unix system.

Sure, when CPUs finally get embedded crypto features (and
applications start using and _insisting_ on their presence) we'll
have problems. For the moment, the technique should work.
