Also, I suspect that the cache could easily be done as a *small* and
*incomplete* cache, ie you don't need to cache all commits, it would
be sufficient to cache a few hundred spread-out commits, and just know
that "from any commit, the cached commit will be quickly reachable".

Put another way: we could do the cache not as a real dynamic entity,
but as something that gets generated at "git clone" time or when
re-packing.

Would it be considered evil if we put the generation number in the
pack, but not consider it part of the formal object (i.e., it would be
just a cache, but one that wouldn't change once the pack was created)?
