Comment (by dank):

 The patch seems to help. Just before applying it, I was able to trigger
 the "phony building" status in 2 of 5 tries. After applying it, I wasn't
 able to trigger it in 7 tries.

 I have been doing 'sleep 6' before 'trial pyflakes', and making the
 reactor.stop immediate; that might have helped trigger the problem. Or
 maybe not.

 The lxc container is ephemeral, so when the oneshot slave exits, the lxc
 container shuts down, and upstart restarts it. So there's about a ten
 second pause before the slave is started up again. It's possible that
 there are short-lived connections sometimes along the way, whether from a
 buildbot quirk or an lxc quirk, or both
