Serg brought this to my attention and asked me to look into it.
Basically, over time we keep adding more and more builders to buildbot and we build an ever increasing number of packages. One way to keep turnaround times for builds reasonable is to add more hardware. Which we are doing by adding a third KVM build host.
However, building every push on every KVM virtual machine is overkill. For example, if one Ubuntu build succeeds, most other Ubuntu builds will also succeed.
From our (Percona) experience, this isn't necessarily the case, different GCC versions etc do catch different things. Every time somebody suggests building on a subset, we find another issue like this (early).... soo... I wonder if you tempt fate the same way we do :) -- Stewart Smith
