Ahhhh.

Yes, we read from the remote and use old->sha1 when doing the
pack generation.  If we do not have that object (in Josef's
example because it is not something we have pulled yet), then
rev-list has no way to create the necessary pack.

I have a feeling this explains what I've been seeing as well.
The first thing I do before I push is to fetch (but not
merge-pull) from kernel.org, but this happens against
www.kernel.org (to make sure people are seeing what I want them
to see), not against master.  So if I happen to do my push cycle
twice before the things propagate from master to www.kernel.org,
_and_ if I happened to have run git prune in my private
repository just before the second cycle, I may end up not having
the objects referenced by "pu" branch there in my private
repository.
