Guido> Intentional.  A module's __dict__ is not emptied when the

Guido> have written) that preserves a cache across relaod() calls:

Guido>     try:
Guido>         cache
Guido>     except NameError:
Guido>         cache = {}

Thanks. I saw that in the doc shortly after posting. I hope you don't mind that I just added that example to the doc.
