Tristan is correct: this should be a patch against Twisted, or perhaps as a separate library that could implement a reactor.

I think there is some confusion here.

I am not writing a competing event driven mechanism. What I was doing was feeling out whether there was any interest in better support for asynchronous calls.

You are right. This should not have been on this list. It should have been on python-ideas, but I replied here because Dustin started the discussion here and I thought if a generator based microthreading solution were to be implemented, it could also benefit from better asynchronous support so brought it into the discussion. After all, if microthreading was in the Python distribution, then it makes sense to make other general improvements which make them more useful.

What I meant to suggest that Twisted could be based on was the asynchronous file IO support using IOCP. Especially because Tristan implied that Twisted's own IOCP reactor was incomplete. I did not say this clearly.

Yes I have looked at Twisted. It was the first place I looked, several months ago, and what drew me to it was the IOCP reactor. However as I also explained in my reply to Tristan it is not suitable for my needs. It is a large dependency and it is a secondary framework. And I did not feel the need to verify the implication that it wasn't ready because this matched my own recollections.

But I hope you realise that asserting that things should be within Twisted without giving any reason, especially when the first person saying it just stated that the matching work in Twisted wasn't even ready, feels like Twisted is trying to push itself forward by bullying people to work within it whenever something can be asserted as laying within whatever domain it is which Twisted covers. Even if it doesn't suit their needs. I don't think Tristan intended that, but when followed up with your reply and JP's interesting response to Greg, it feels like it.
