Without commenting on everything else in the thread - this realisation 
was something I came to late, and I feel it would have helped enormously 
if it had come earlier. So, +1 on convincing people to go for in-memory 
/ simulated transport/clock/etc.

But I'll note that most people I've seen crib from existing test code 
during the early phases of TDD, tutorials or not - and if most test code 
in Twisted uses the real reactor...
