Noted, though I doubt a major version jump is in the cards for that
machine in the foreseeable future.

And, really, because it still needs to run in the original pre-MP
kernel with minimal changes, what I'm going to be doing is pulling all
the locking out so those differences can be hidden from everything but
a relatively small and well-defined piece of the code, making further
ports to the locking scheme du jour relatively simple.
