[Zope] Xron on Zope v.2.3.1

[Loren Stafford]

Upon rereading this message, I realized that you suspect that you've run
into the "Xron locking up my system on startup" bug. However, that problem
only occurs the first time you restart Zope after installing Xron, when Xron
tries to create the Scheduler catalog. It creates a deadlock that keeps the
entire Zope system from progressing out of the product loading phase. But if
the rest of your Zope installation is working normally, then you haven't
encountered that specific problem. I would look elsewhere.

Try to get STUPID_LOG_FILE working. That'll give you more info more easily
than you can any other way (unless you LIKE pdb-ing 8-).
