Kristian, AM_MAKEFLAGS is a nice feature in the build scripts, but there's one problem with it - we also have branches in buildbot that do not support AM_MAKEFLAGS. For example, mysql-5.1-testing, but I suppose it's not the only one.
Right. What I did was to set up a different scheduler for archivist's build slaves. This scheduler only runs for the most important branches, so it will put less of a toll on his machines (which he also needs for other purposes). And we can move other hosts there with similar restrictions on load.
What can we do ? Add AM_MAKEFLAGS support to mysql-5.1-testing and other branches, it should be pretty safe. Or implement a more robust limiting of buildbot slave resources, that does not depend on cooperating build scripts.
We could, though mysql-5.1-testing has the special purpose of being an unmodified MySQL branch. But for now we don't really need to, as a side effect of the above change is that all branches currently run on archivist's build hosts support AM_MAKEFLAGS. - Kristian.
