There are outstanding issues that need to be resolved:

 * We need to do something about "gc --aggressive".  The documentation
   removal patch from Linus, if it ever materializes, would be better
   than nothing, but I have this nagging suspicion that the explosion is
   merely a bad interation between -A and -f option to the repack, which
   are not meant to be used together.

Well, with the gcc repo, simply using 'git repack -a -f' with current 
default window size does produce a 2.1GB pack, while changing the window 
size to 100 (keeping default delta depth) produces a 400MB pack for me.

So this is really a matter of not having a sufficiently large window for 
some data sets.

So my dumb patch to simply default to window and depth 250 with 
aggressive was not _that_ dumb after all?

Probably not, although this might be rather wasteful on some 
repositories.  But that's what expectations are for --aggressive.

I wish we could find a way to set some good window default dynamically 
though.  Or perhaps the filename hashing needs improvements.
