[squid-users] squid3 configure options question

The debian/unstable squid3 packages are configured using:
...
 --enable-storeio="ufs,aufs,coss" \
 --enable-diskio="AIO,Blocking,DiskDaemon,DiskThreads" \
...

What exactly does "--enable-diskio" do? I notice that the
"--enable-storeio" option doesn't include "diskd" anymore, but
"DiskDaemon" in --enable-diskio sounds similar.

I can use the different storage types specified in --enable-storeio
e.g. in the cache_dir config option, but how and where do I used the
stuff from --enable-diskio?
