[Twisted-Python] Caching mechanism

[Andy Fundinger]

Twisted doesn't enforce any, that's part of the effect of you actually
writing the server, defining, enforcing, and adhering to those limits is
left to the developer.  Of course you have a limited amount of space in your
machine, and you probably don't want to use swap, but nothing twisted is
going to limit you on, it doesn't really do anything on that level of
abstraction.

Drinking good coffee makes you wise, drinking bad coffee only makes you
awake.
