This isn't just a related subject, this is exactly what
I was trying to do above.

I have a test case here which is failing, however, because
the exception is *not* being delivered asynchronously for
some reason, but appears in the thread only when the thread
is already terminating itself.  I'm still experimenting, but
I will probably post the failing test case shortly for
others to play with.

Nick, if you want to learn more, read the threads from this
google search: http://groups.google.ca/groups?q=PyThreadState_SetAsyncExc

Then you'll know as much as anyone about this...
