[Zope] Strange Zope errors with heavy use of SESSION

[Chris McDonough]

Here is a description of the error that the OS is raising which results
in this traceback:

I'm not sure how the sessioning code could cause this, but it's possible
it's some sort of platform-specific behavior.  Is it 98, ME, W2K?  I'd
like to try to replicate it.
