[Zope] - external methods and pickling

[Wolf Logan]

i think i have finally figured out why the code i published earlier was
failing. apparently it's a serious incompatibility between my library code
and zope. for now, i have to abandon zope and stick with zpublisher, which
i'm only now beginning to get installed.

basically, part of my library code unpickles a class instance from a stream
over a socket. this works fine usually, but apparently it just doesn't work
inside zope. zope's unpickler is "different" enough that it can't unpickle
this class, and the code crashes with the error i reported eariler.

i've tried changing my code to use a different unpickler, so as not to
collide with zope, but it didn't help. i don't know enough about the
persistant object system to fix the problem, and i'm running smack into a
major deadline. if anybody has any ideas, i'd love to hear 'em.
