I copied your code verbatim and I don't have any issues with it at
all. Same version of Python, same version of Apache.

In SimpleXMLRPCServer.py, register_function adds directly to a
self.funcs dictionary, so an instance variable of the same name
shouldn't hurt anything.  That exception is only raised when a
self.funcs lookup raises a KeyError unless you're registering an
instance.
