I hadn't been using it since the docs say you usually don't need it.
This fixes my problems win PythonWin. SPE chokes now when the program
exits, but it doesn't seem to choke in the same way as before. Thanks
for suggesting this!
This still isn't going to be a great solution. If your program errors out
with any exceptions or problems, your PythonWin session will likely be
broken. This is mainly a PythonWin problem. It runs the program it is
debugging in the same process as the editor. This makes it very easy for any
program to break the editor, and any graphical programs or gui's will
definitely break.
