persistent deque

[inhahe]

oh yeah!  thanks for pointing it out, i should have thought of that, i 
*just* read about it today, or was it yesterday.

so what's the problem with pickle?  i have a feeling, maybe i read it, that 
when you pickle a derived class it pickles it as a member of the base class, 
is that it?

i don't know how i would get around the problem, though, because i'd have to 
know how to access the deque object that my class stores when i do 
deque.__init__ in my constructor, so that i could pickle it and my class 
variables separately.
