Re: [RFC] git-fetch - repack in the background after fetching

Some long-running (in git terms) git programs will look up the pack-files

there, and will be very unhappy indeed.

We should be able to fix this, right? If an object isn't found in packs or 
unpacked, look for new packs; if there are any, look for the object in 
them; if it's not there, then give up. The only tricky thing is making it 
possible to scan through the available packs without installing any that 
are already installed. I think the failure case is only a critical path in 
the history-walking fetch code, which should probably disable this (or 
defer it to after trying to download the object).
