[Twisted-Python] Caching mechanism

Part of the beauty of twisted is that you don't actually need to do anything
special to achieve that, just create a global dict or other object of your
choice and access it as needed. More likely what you need to look for is a
cache expiration mechanism, I've linked in lrucache (
http://pypi.python.org/pypi/lrucache/0.2) in one case, but usually I just
write my own constraints as appropriate.
It's often misunderstood, but in twisted you are writing an actual server
rather than just some methods for servicing requests. The server will run
until stopped and all global or even local variables will remain in memory
unless deleted or dereferenced and garbage collected. Rather than doing
something special to get a persistent variable you need to do something
special when you want a non-persistent one.
