[Zope] Refresh ZEO interactive python when changing product's code? Was: Adding __setitem__

[Jeff Kowalczyk]

FWIW, that problem with "AttributeError: __setitem__" was that my console (PythonWin
connected via ZEO) isn't aware of product refreshes. I'm kind of in uncharted territory
here (for me), but what should I be doing to get the python console to recognize the
updated python product code when I run a refresh from the ZEO-connected Zope ZMI? Here's a
sample console problem demonstrating the symptoms, and some of the things I've tried to
avoid closing out the python console each time I change python code in a product. Thanks
for any help anyone can offer.

This is probing how to get the console to recognize that __setitem__'s implementation has
changed from 'print test1' to 'print test2' after the first call.

PythonWin 2.1.3 (#35, Apr  8 2002, 17:47:50) [MSC 32 bit (Intel)] on win32.
