I guess that, for now, this method should convert it's
names to a list if it isn't one already. Of, course, 
listing all the names in a 1200-user database is lame, 
but we have to live with this lamosity for now.

Shane, can you fix this?

Actually, the user folder was changed to use a BTree rather
than a dictionary. Shane did that with my, um, guidence.
The use of a dictionary caused the site to have too many
objects in the cache.

Note that you can now use ZEO to do this sort of thing.
Basically, go to the lib/python directory and:

  INSTANCE_HOME=/usr/local/dc/org python
  import Zope
  app=Zope.app()
  .....
  get_transaction().commit()

Because zope.org is running ZEO (we still need to change the
mounted wikis to use ZEO) you can get to the process from Python
without shutting it down! This is much better than using the 
monitor client.
