the core, but it doesn't, so to some extent you're on your own.
However, if there is no official "design pattern", there are certain
trends which have been repeating themselves. Twisted's
twisted.application.strports and twisted.spread.pb, as well as Divmod's

conveniently with one line of code, and provide at least some basis for
abstracting the components of that line so that they can be plugged in.
PB's method is "login", strports has 'service' and 'listen', and Q2Q has
