The code is intended to run single thread so we never have done anything
about threading. It's a real pain. In a zope world we ought really to
give every request a fresh context ie each thread would see an entirely
'clean' python and then be forced to load its own fonts/resources. It
just sucks from the overall system viewpoint. How does one ensure that
each thread sees its own version of sys.modules etc etc or is that
considered a dumb question?
