semi-automatically... that is automatically but with human
supervision... has mishap need to be caugh and fixed early
I imagine that there would be a log of a few days... maybe a week
between the head of a branch and the bibisect repo..
if for no other reason that git gc does a better job if it has many
loose object to compact, compression wise
and doing git gcc --aggressive to balance that once in a while is
prohibitively expensive... and as the repo become build, won;t even
run on most machines

we can't.. 2500 build for the 4-2 dev period... mutliplied by 200MB
taht is 500GB for Mac alone
and that is just for the period May-December 2013
that is 5GB in a bibisect repo...

because I can rebuild _some_ missing section... and stich the rest
using the tarball
I've been doing that dance for the past 3 weeks building the Mac bibisect

no it won't. we already have tinderbox that send email when stuff
breaks.. but sometimes some tb are out-of-order, sometimes stuff get
overlooked, sometimes shit happens etc...
iow bibisect will not help us to detect that something does not
build... sicne we build far more often than we aggregate bibisect
