[Zope] Transience Error

[Jim Kutter]

Hi Boys and Girls. Major bad news. I have serious problems with the
Transience (specifically the sessioning mechanism) snarfing under high
loads. Now before you jump to the rescue and mention the patch, I have
already installed it, and no luck.

What can I do to either reduce the load or circumvent this problem?

Here's the traceback...
