[Zope] - evaluation of external methods

[David Ascher]

When external methods are added or updated, the Python code in their
module is evaluated in some (obscure to me) way.  The current working
directory at the time of evaluation is not the same as the current working
directory when the method is invoked. This has forced me to move some
things inside of functions instead of at the module-level.  Is this a bug
or a feature?
