Re: git-index-pack really does suck..

I'll buy that.  ;-)
 

Which leaves us with the actual pack index lookup.  At that point the 
cost of finding an existing object and finding that a given object 
doesn't exist is about the same thing, isn't it?

Here's the rub:  in the missing object case we didn't find it
in the pack index, but it could be loose.  That's one failed
syscall per object if the object isn't loose.  If the object
isn't loose, it could be that it was *just* removed by a
running prune-packed, and the packfile that it was moved
to was created after we scanned for packfiles, so time to
rescan...
