Phew.  ;)

Well, my belief is that it's growing without bounds.  It starts at
13M, jumps to 18M and then gets progressively higher.  It used to grow
up to 30M-50M or so.

I'm currently experimenting with reducing cache size/time (target=50
objects / time=10s currently) but I'm not sure that helps yet.  It
seems to have improved the situation slightly, but we'll only be able
to tell in a few hours.

Don't worry, I'll fight it. ;-)

Thanks for the amazingly quick response!
