Yeah, it'd be cool to have a bibisect repo that's automatically updated
by a bot. Also neat would be to take the various installs generated from
it and get some numbers like change in startup time, install size,
memory foot print of the apps over time.

If 15MB per install is a constant, then daily builds for a year would be
about 5 and a half gigs. Practical numbers ?. Do a different repo per
year to keep each one manageable ? 

I guess a 32bit build might be more universally useful rather than a
64bit one. Rewind back to the start of the first successful build in 
Bjoern's repo and build from there again ?
