I don't think it's reasonable to ask buildfarm owners to set up their
animals like that, because (AFAIK) it requires tedious, error-prone
configuration of moving parts that we don't supply, like cron scripts.

If there were some trivial way to do that, it'd be more acceptable.
Maybe invent a build-farm.conf option like "newest_branch_to_build"?
branches_to_build covers some adjacent territory, but its filtering
options go the wrong way (only branches newer than X, whereas what
we want here is only branches older than X); probably we could
also address this with more options there.
