Converting my messages on IRC into a real issue:

2:09:50 PM Hexcles Weird OOM issue: https://tools.taskcluster.net/groups/MSv-O1xKTEm6uQwSEKcBlQ/tasks/UjYVhjduTUCT63_f-hM1DA/runs/0/logs/public%2Flogs%2Flive.log#L521
2:10:31 PM Hexcles What can possibly use almost 7GB of memory BEFORE the tests even start?
2:12:59 PM Hexcles The worker ran out of the 7GB memory at this line https://github.com/web-platform-tests/wpt/blob/master/tools/ci/start.sh#L27 , before starting wpt...
2:15:00 PM Hexcles Another example (in the same task group): https://tools.taskcluster.net/groups/MSv-O1xKTEm6uQwSEKcBlQ/tasks/FpuFoMecSriaRxfutjsTag/runs/0/logs/public%2Flogs%2Flive.log#L147
2:16:16 PM jgraham The latter isn't obviously the same problem?
2:16:43 PM Hexcles jgraham: yes. gpgv was killed because of OOM, and the package wasn't installed.

No clear clue what's happening here, so let's create an issue and keep an eye on it.

Doesn't seem to happen again in the past few days. Setting the priority to backlog until it happens again.
