[Zope] Zope 2.9 Product Refreshing

[John Schinnerer]

Since I never knew the refresh tab was a fragile hack, it always worked 
fine for me... :-)

Are you saying that a "really good" solution for this is in the hands of 
python developers, not zope developers?
In that case it seems far off, if ever, since zope is only one of many 
many applications using python.
I would settle for another fragile hack that works, I guess.
The volume of posts so far would seem to indicate that it's not a 
trivial topic...
