Why've you got enable-poll, enable-select, and enable-kqueue? :) Anyway.

You won't have one by default.

Squid rebuilds COSS async but it will do it by reading the entire COSS file in
from start to finish. Its not efficient at all. Try running iostat or
systat -vmstat 1 whilst its rebuilding and see if you've saturating the disk
IO.

I'm sorry guys, I just don't have the time to work on fixing up COSS past its
current state at this present time.
