OK, I'm convinced. I believe I know how to make the Algorithmics
emulator SMP-safe *and* more efficient in the general case, thanks
in part to a suggestion from Ralf. Time permitting, I will also wire it
up to the unimplemented operation handler. Give me a week or so
to accumulate enough spare time...
