Thanks, Robin! To be very specific about one of the above, the Gnome box 
is a dual-CPU with 8G RAM on some kind of RAID. Owen Taylor (otaylor on 
IRC) informed me that it handled git with no problem at insignicant 
load.

OTOH, I don't know of anyone with a repo more than 1/2 the size of ours 
and maybe 1/4 the object count. My local clone of the kernel is ~600M.
