So I have submitted and updated a patch here: http://twistedmatrix.com/trac/ticket/5228 And I was wondering about writing the project proposal. I'm interested in the Deferred Cancellation idea, but not married to it. The GSoC page says that the proposal should be written with a mentor from Twisted. Is that still true? If not, are there any particular things you're looking for in the proposal, other than what's listed by Google in the requirements? Thanks a lot, Max Haarhaus
