It is true that if you do not have huge working directories checked
out this should not be such a problem. Unfortunately that is not
something that I can enforce easily in our setup (for several, mostly
political reasons).

BTW, what do you mean by "long lived process". I got the impression
that when using CGI each request required a new execution of mercurial
on the server. Is that not the case? I do not know about
"refreshinterval" either. When you guys helped me improve the
performance of our server Matt himself told me that mercurial does a
repository search on every request (even when accessing a particular
repo). I may have misunderstood him, though.
