Ok, I'm following this. Just been off my PC for 18 hours. I'm up for
doing things properly (unlike some of my previous, um, code dumps).

I've had some practice figuring out tests, I've had a look at the
coding standard and I'm happy to have a go at some documentation.

I'm finally getting the patch+test coverage message especially as
several of the existing tests (after I enabled them) pointed out
short-comings in the code as I was working on it.

I should be able to get something together in the next day or two, right
now I need some sleep.

Thanks for your helpful reponses, I'm keen to make a useful contribution
to Twisted as it has served me well over the years,

best regards,
