Hmm. It's definitely something I plan to keep in my head.  I'm a little wary 
of mucking with the interpreter at that level (that warning about "naive 
use" of PyThreadState_SetAsyncExc in the documentation definitely would 
apply to my knowledge level of python internals at this point). However, I 
may end up having to...

For now, though, trying to get the threads to exit cleanly is an aesthetic 
thing (a flag and sys.exit() does the job, albeit with the occasional 
exception when a thread doesn't check it's flag in time). Heck just going 
into process explorer and killing the thing is acceptable at this stage. But 
this may change, and I'll be searching for this e-mail again....

Thanks for the tip!
