I'm not at all interested in this topic, but in the time it took the two
of you to write your emails, I did this:
$ cd linux-2.6
$ time git verify-pack \
.git/objects/pack/pack-36c50f6082df404c26a699f2702946e0cce6208f.idx
real 2m37.338s
user 2m35.874s
sys 0m1.348s
$ time git index-pack --verify \
.git/objects/pack/pack-36c50f6082df404c26a699f2702946e0cce6208f.pack

OK, with the CPU time it probably took longer than your emails. But I
ate some ice cream while it computed. :)
I guess my box is showing its age. It is 2m34s vs 3m25s for the kernel
repository packed with depth=50 (the default).
A pack created with insanely deep depth of course shows larger difference
(2m31s vs 4m38s for the same repository repacked with depth=8192).
