I have a few lines of code that runs a debug-server in its own thread,
listening on a socket, and exec-ing text that is sent to the socket.
The exec happens in the debug-server thread.
It's very useful - you can get a backtrace for all threads (on
python-2.5 and later), look at globals, call functions, etc etc, all
while the main programme is running.
If anyone's interested, i'll put the code somewhere. It's all very
simple; some would say crude, too.
