[ --enable-async-io[=N_THREADS]
                          Shorthand for

therefore if you want to increase the number of threads avaliable to asyncio
simply add --with-aio-threads=N .

COSS stands for "Cyclic Object Storage System". Its a cyclic FS written
by Eric Stern a while back. It is more of an experiemnt - currently it
isn't async, so its usefulness is currently limited.

I'll get around to converting it to use async disk IO at a later stage,
but I think we want to get squid-2.4 out first.
