A bit of both. I've implemented a comm_read() / comm_write() /
comm_listen() which take callbacks. This is esp nice for say, kqueue -
we can set the event on the listen FDs as continuous, and not have to
re-register an IO completion every time we want to accept a socket.
We just call comm_listen() with a callback like you did, and its
all good.

Ok. How about this.

I'll document what I think the disk layer should look like.
How about you document how the network layer should look like.
Robert - how about you document how the request/reply layer should
look like.

I'll collate, stick on the squid website somewhere, and we can
discuss any pitfalls. Once we've got something in rough shape
we can knock together some quick code to test the idea out with,
and proceed from there. I'd like to avoid the committee-type
pitfalls.

(Finally, some work? :-)
