Re: Doing everything asynchronously

I'd be curious to know if there are any other open source news readers
that do this ... do as much work concurrently (multi-threaded) or
asynchronously (single or multi-threaded) ahead of time while waiting
for user input.

It's a very different architecture, but in my Newsgrouper (web gateway to
usenet) I prefetch various things.  E.g when a user enters a discussion
thread I queue up jobs to prefetch any new articles in that thread.
These jobs are then processed by separate "newsgetter" processes which
write them into a Redis cache so they can be returned immediately if the
user goes on to read them.  I run 4 newsgetter processes, each has an nntp
connection to the usenet server, so multiple articles can be fetched in
parallel.  The code is at:
