I had intended to include an example around "likely to be quite a short 
list". Because I happen to be plotting data this today and I've imported 
matplotlib. Now:

    >>> len(sorted(sys.modules.keys()))
    1381

Ouch!

Still, your modules is a list of names from source code, not the 
sys.modules dict. So probably small still.
