We've got a number of websites on one of our production servers, and they
get hit moderately (it's not Amazon... but they are US gov't scientific
research sites), and I think we've got 25 threads running, total, to
server *all* of them.

Ah! I missed that. Is it actually the case that your server doesn't even
have 2G of RAM? That's a *real* problem. If you're not running it on a
five year old desktop, you need to add - I'd say you shouldn't be running
with under 4GB of real memory.
