Feature request: Babysitter of slow clients

I have a web application that doesn't generate any cachable content, but
varnish could help in one respect; The apache processes use gobs of
memory, so maxclients has to be low, but once a page has been generated
they have to wait around for the slow clients to fetch all of the
content before they can get back to producing new content.

Varnish could help in this situation by quickly slurping up the content
from apache, so it can return to work and passing the content to the
client at the clients pace.

Doesn't it already? (I haven't tried Varnish yet, but that would be
one of the Must Have features). I am at the Web Builder conference
and I'm just told a bunch of people in my talk to use Varnish for
this in 2007. :^) (The slides are at http://develooper.com/talks/ )

If you don't need caching, then perlbal has some of the same
properties as Varnish and it does do the "slow feeding to clients"
thing. (And Keep-Alive connections in both directions).

Only when it caches, in pass mode it doesn't (yet).
