LA of build servers would be significantly less if we stopped building
a lot of broken packages again and again for every quarter release.
graphics/evas, for example, is broken for years, x11/qt4-creator --
for several months. There are a lot of similar examples.
Such packages waste a lot of machine power. In order to solve this problem
in distbb I recently added -a option (not released yet).
If -a is applied, distbb builds the specified packages only
and resulting pkg_summary and SHA512 are *updated*.
This is how last amd64/5.1/2012Q1 bulk built looks like

If you see "really built" packages, i'll find databases/mysql55-server
and databases/mysql55-client packages only. On dual core Atom-330
the build took 70 minutes.

I have a plan to embed 'cvs up' output analyser/heiristics into distbb
in order efficiently calculate a list of packages to rebuild (usually
a few of them). This heiristics should
analyse "P category/package/Makefile" entries for examples as well as
"P category/package/buildlink3.mk" and so on.
