I started using Python for come user CLI stuff. It has worked out so
well that we're thinking about extending it's use in our project.
I am not experienced enough to be able to answer some of the issues that
came up. Does anyone have any thoughts on these:

Multi-threading, and mutual exclusion. Are these available, reliable,
and debuggable?

thanks, Bruce.
