Yikes. This is not even remotely a fair comparison to monotone, which is keeping a central db.

It's much better than that. I just cloned

  git://github.com/felipec/pidgin-clone.git

and the _whole thing_ is 148M, including the working tree. His object db is only 88M. So he can do his 11 trees in 61 * 11 + 88 = 759M, saving 141M over monotone.

And I am repacking with insane depth and window right now to see if we can get it smaller (though really, it is not that big a deal, since the size is dominated by his 11 working trees).
