Windows 8, msysGit.
git repack -adf on msysgit/git (best of 3 runs)
+ nedalloc: 10.5s
- nedalloc: 11s
git repack -adf on torvalds/linux (best of 3 runs)
+ nedalloc: 3m 24s
- nedalloc: 3m 47s
We need to make a decision: drop nedalloc, update nedalloc to later release,
patch nedalloc to make it work under MinGW-W64 or disable nedalloc under
MinGW-W64 (still leaving it enabled under MinGW).
P.S. Waiting for "Resolving deltas" when cloning torvalds/linux is a pain,
perhaps someone should run gprof on it.
