I have further information on my problem of unpickling an object that 
is based on Numeric.UserArray class.

I can recreate the endless getattr loop with the following code, 
which is a small subsection of my class:

data = Numeric.ones(31,savespace=1)
ua = UserArray(data)
blob = cPickle.dumps(ua)
obj = cPickle.loads(blob)      <-- fails here

If you pickle the data obj, everything works.  This code works in 
Python2.2.

Is this a bug?  Is it fixable?
