:jdescottes can you please take a look at this?

This seems to have spiked just after we landed the test browser_aboutdebugging_serviceworker_fetch_flag.js which runs right before this one. I did a few try pushes to try and understand what was causing this, but I didn't manage to get a single failure yet. Will try again with linux debug.

Since the failures are mostly on debug builds, if we can't find anything, we may skip it on debug for now to reduce the noise.

bug 1517210 may make this slightly more intermittent.
It may be related to unexpected GC behavior where the GC isn't being triggered frequently enough and leads to OOM crashes.

Fails primarily on asan and debug. Have sent try pushes to try fo force GC to see if it helps.
Main worry is that if this is GC related, skipping the test might just move the intermittent to the next test.

Retriggered the wrong job here, because the skip-if modified the chunks. The dt3 failures in this push are not relevant. The test is running in dt7 here.

Edit: Retriggers on dt7 are finished, no failure in the aboutdebugging-new tests. I think it's safe to move forward with the patch attached here. The GC patches didn't fix the intermittent (one of them might have reduced the frequency, but needs more retriggers)
