Kinda have test working -- assembly looks right for saving core loop frame and stack
and restoring them
But have a bug that looks timing-related, so thinking maybe some threads are going to
completion?  The whole test isn't quite right yet -- it throws exception because the
suspended virtual processors never have a continuation put back into the workQ
(is this right?  Is that why it throws exception?)
Want to move to full code to finish debugging
