What is a "sane" setting for maxdsize when running amd64? it
seems many normal suggestions do not apply.

This could be said of a lot of software, including many Unix
I can think of several things to criticise about Squid-- a config
file which falls between Apache's httpd.conf and a sendmail.cf in
terms of complexity is probably close to the top of my list, but for
the simple purpose of saving limited network bandwidth using on-disk
or in-memory caching, squid does just fine. I'd be happy to look at
Varnish when I get a chance, though.

OK. Nicole, the OP, mentioned "amd64", not "-CURRENT", but I'll keep
this in mind for future reference.
