You are (at least as I recall from past messages) in the rather
pathological case of wanting to semi-permanently use a large archive
for a large tree but almost always use that archive remotely over a
relatively slow link. So, yeah, that edge case is nasty for you.

Right. I'm guessing you're being dominated by O(N) round-trips
when patching against patch-N. Various archive-side caching/memoizing
hacks can bring that way down. (It's also worth double checking, of
course, that it really is what I think it is....)
