See the purple job on https://codereview.chromium.org/2738253002/

Maybe the 2h timeout is too low, but all the other bots completed much faster.

Compare:

https://build.chromium.org/p/tryserver.chromium.linux/builders/linux_chromium_chromeos_dbg_ng/builds/1082

So it's probably some bot config thing. And compile was 49 min on both bots, so it's probably not related to goma.

Not sure who's a good owner for this.
