The original was not designed to be thread-safe.  I'm not sure if Mike
changed anything in the current version to make it so, but I doubt
it.  I don't know too much about threading with Python, so I'm not
sure how hard it would be to make the dispatching thread-safe.  If it
could be done rather simply and elegantly I'm sure we'd love to have a
patch that adds this feature.
