[Twisted-Python] Avoid circullair dependencies.

Sounds like you could use a lazy import. I do something similar to this in
my factory:
# protocol.py
class MyProtocol(XmlStream):
....
class MyFactory:
def buildProtocol(self, addr):
myProtocol = MyProtocol()
# heres the lazy import
from othermodule import SomeKlass
SomeKlass(myProtocol)
My `othermodule' imports some constants from `protocol' (module defined
above). So, to kill the circular references, I do a lazy import in
MyFactory.
HTH!
