Re: [PATCH 0/5] Suggested for PU: revision caching system to significantly speed up packing/walking

Hrmm, I just realized that it dosn't actually cache paths/names...
This obviously has no bearing on its use in packing, but I should
either add that in or restrict usage in non-packing-related walks.
Weird how things like that escape you.

I think I may go ahead and add support for this tomorrow.  It should
have no effect on performance and very little impact on cache slice
size.

You may not need the path name, but instead the hash value that
pack-objects computes from the path name.  All that matters is
the hash, so pack-objects can schedule the objects into the right
buckets when its doing delta computation for objects which are not
yet delta compressed, or whose delta cannot be suitably reused.
