Hi,

git 1.4.0, P4 2.6GHz, 1GB.

I'm trying to use "git prune" to remove some unreachable objects from
my git tree.  However, it appears to be _extremely_ expensive:

rmk      13376 91.3 15.7 165980 161556 pts/0   R+   09:50   5:14 git-fsck-object

stracing it shows that it's doing lots and lots of brk() calls.

I killed it after 10 minutes and decided to do the job manually -
git-fsck-objects --unreachable and deleting the objects one by one is
_much_ quicker than git-fsck-objects --full --cache --unreachable.
