Yup, it uses the POSIX aio calls. You'll need to find support for this
somewhere. I know for a fact that FreeBSD and Solaris support it.

* Grab the diskio branch from sourceforge
* Use a config file that looks something like this:

coredump_dir /home/adrian/work/squid/run/logs
cache_dir coss /home/adrian/work/squid/run/coss-1 100 max-objsize=65536
cache_swap_log /home/adrian/work/squid/run/cachelog/dir.%s

I think the last line will do it- just play with it a little.

the diskio branch has the COSS code from HEAD, the sdirno/sfileno types
modified to be 2gb-happy (don't go over a dirsize of 2000 just yet..)
and some zero-copy store client patches which I'm going to need to
develop to get some efficient read code in there.

Don't try to talk to a raw disk just yet either. It will work in theory,
but it might run like _crap_, if it runs at all.

Good luck!
