Because we didn't have enough build slaves floating around?

Are we currently under buildslave crunch for the paladins?

master: https://uberchromegw.corp.google.com/i/chromeos/builders/master-paladin/builds/14162
late started monroe: https://uberchromegw.corp.google.com/i/chromeos/builders/monroe-paladin/builds/12806

The monroe build got killed because it started only a few minutes before master finished (and the next one killed the monroe build)

I know I've seen something similar before...
