Details

In bug 1594878, I made the browser/components/uitour/test/ directory preserve processes, in an attempt to fix frequent intermittent hangs. We should figure out what the actual source of those hangs is, fix it, then remove the pref set of dom.ipc.keepProcessesAlive.webIsolated.perOrigin for that directory.

Fission Milestone: --- → M4.1

Andrew, do you think these intermittent shutdown hangs need to block the Fission mochitests milestone (M4.1)?

Flags: needinfo?(continuation)

The workaround of reusing Fission processes seems to have stopped the issue from showing up on TreeHerder, and hasn't popped up in a while, so I think we don't need to track this for M4.1 any more.

I am concerned that there's some real hang issues related to this that we might see in the wild, but I think we can ignore that until we get telemetry or whatever showing it. But if we do, it would be good to keep these issues we've seen in testing in mind.

Thanks. Tracking for Fission riding the trains to Beta (M7) after we see how much of a problem this is with more users.
