Yes, I do use the threading module, but it's not quite that simple. Some of my threads are actually running Java code, for PyLucene.
This is part of UpLib, at http://uplib.parc.com/. Thanks for the pointers. Is there a home site for rpdb2? Or is it just part of winpdb? The nice thing about gdb is that it doesn't need to be "on top"; you can attach to a server you started without any magic invocation. UpLib has a complicated startup dance, and it's hard to start it with the kind of invocation needed for debuggers like rpdb2.
