ESI is still not production ready, the modular disk IO stuff is a good
start but there's still legacy code (src/disk.cc) which implemented
the whole original "modular" code (sync or pthread-aio) which was
made less useful when the store io stuff was split back in 2.3/2.4 days.

Yes, but the internals are still ugly. I don't think the current state of
the delay pool "hooks" into Squid, especially in the comm mess, is actually
the way to go. Unfortunately there's little motivation to fix up this
stuff.
