This is an interesting idea... so I went through the <<silly>> exercise of
downloading 117 tar bzipped versions of the kernel 2.6 (from 2.6.0 to
2.6.19.2, without the release candidates). Quite an interesting
benchmark.

Then I started importing them, through a similar script, creating a
branch for each version (for easy checkout). It takes around
1.5 hours to complete.

Results:
======

initial point: 4.3Gb of tar.bz2 files

intermediate: ~800Mb with ~120000 git objects

final point: 100Mb with prune-packed objects
(so it's about 2.5x the average tar.bz2 size of just a single kernel)
