[Zope-xml] Trying to get 4Suite and XMLTransform up and running

[Craeg K Strong]

Hello:

I had a thought.  Have you tried changing the number of threads you use?
According to your command line, you are restricting zope to a single
thread.  I am starting zope using all of the defaults:

/usr/bin/python2.1.3 /usr/local/zope/2-5-1/z2.py -D

according to z2.py, the default number of threads is 4.
Maybe that's the problem?   It could be that these external
libraries require additional threads....
