True -- I am of the opinion that threads should be cooperatively stoppable,
but not preemptively stoppable, if that makes sense.  Asynchronous exceptions
are the ideal way of implementing this, since the main interpreter loop is
essentially already instrumented to handle them.

Ah.. that sounds familiar.  I knew there was a reason I didn't pursue this
avenue farther last time I poked through that code.
