I think adding another except clause for KeyboardInterrupt isn't good
because maybe in Python 2.6 or 2.6 or whatever there will be some
additional exceptions like that and your code will break.  For example,
proposals have floated for years of adding ways for threads to raise
exceptions in other threads.

I put up a proposal for adding an AsynchronousException class to
contain all of these types of exceptions, so you can check for that.

The solution to that one is obvious.  We have to get Knuth using Python.
Anyone want to write a PEP?  ;-)
