The issue here is that the main thread exits while the sub-threads are
still running and inside the debugger sub-threads are killed when the
main thread exits.  You can work around this by adding something like
this at the end of the code:

import time
time.sleep(10)

We'll try to fix this but there were some subtleties involved that I
need to look up and understand again.
