Re: faster client pre-1.0: neon prefetching, multithreading

after reading a little in the code, i could not really figure out
where you could place the aio calls, and where exactly place the
aio_suspend. do you mean in neon, or outside?

Easier to use AIO when it's available.

You can just aio_read the sockets/disk stuff as we discover what we
need, then aio_suspend in the routine that actually needs the data to

wait for it all to get there (or a timeout to occur).

Once again, you can just aio_read this stuff, then wait for it all to

finish at once, rather than wait on them one at a time.
