Yet it doesn't - that might be one of the reasons why 1.10 isn't stable in 
Gentoo, yet.

The biggest thing which keeps me from running the tests far more often are the 
10 minutes bzr needs to get the initial repository - the time feels so damn 
long :) 

And I don't keep one around, because 215MiB aren't so little data when I'm at 
the limits of my disks capacity. 

But here's the retest (done manually):

That's 17 seconds, far from the 2-4 seconds it gained with the --rich-root-
pack setting.
