That wheel is far from round, and needs some reinvention. Python's
file-like objects do not play nice with lower level calls, which
would be tolerable if they supported some well-defiend high-level
asynchronous I/O, but they do not.

Yes, but there's a world of gotcha's. Sockets do not recognize
record boundaries, and Python's 'pickle' has holes one's enemies
could drive a truck through. Still, you can pickle, write, read,
un-pickle, and get back your data intact.

"Two pickles" sounds like a tasty snack, but also suggests you may
be playing hopscotch in a minefield. This is a helpful group. Give
us more to go on, and you are likely to receive thousands of
dollars worth of consulting for free.
