Don't worry to much.

The current async-io code is there, but the design of it can't be
brought much further than it is. The current code quickly makes the CPU
a bottleneck.

Yes, there are activities in finding a suitable replacement, both for
the I/O and the actual storage.

What Alex refers to is that I have now officially ended my attempts in
getting the current async-io code to perform better and more stable in
high workloads, and will instead spend my time on a different approach
to the problem, when time permits that is.

The net effect is that the async-io in Squid 2.3 may not perform as well
or stable a in patched Squid-2.2, but in time there will be other
alternatives which hopefully perform better, even thou it may take some
time before everything is in place.
