I see, and agree. However, that can already be dealt with on the build
master side, i.e. via coordinated scheduling and locking.
This raises another interesting issue that I have brought up here on
numerous times (but unfortunately without sufficient insight and time to
address it myself): load balancing, i.e. the ability for the build
master to pick among a set of 'equal' slaves, depending on their load.
(Note that not all of the load may stem from builders, so it is
important to monitor resource usage that's coming from external tasks
not under control of a buildbot instance.
