I see no other way to have the buildbot auto-detect broken packages to
rebuild them (which would free us from having to revbump manually, which
is something we want, right?)

The process could probably be optimized to activate sets of
non-conflicting packages at the same time (I'm thinking graph coloring).

The time-consuming part would probably be activating and deactivating,
since updating the binary database would not be necessary (the
information is already in the registry on the buildbot) and scanning
should be rather quick, since only these packages and their dependencies
are installed. So in conclusion, the whole process would probably be
I/O-bound.

The case that rev-upgrade actually finds problems and triggers rebuilds
would probably be rather uncommon (how many of the changes you commited
required revbumps?)
