Details

(Whiteboard: [fxperf:p1])

After Bug 1610134, we now call BeginLateWriteChecks if we ever exceed the toolkit.asyncshutdown.report_writes_after pref, which is currently set to 20s. We need to ensure this is a sufficient number to set the pref at.

If it hits this pref, the results will be reported through the lateWrite telemetry information in the "isFromTerminatorWatchdog" portion of the JSON object. The goal is to determine a pref value to ensure we can actually shut down when we are indefinitely hung as opposed to just shutting down more frequently.

Summary: Reduce toolkit.asyncshutdown.report_writes_after pref to crash earlier in hung shutdown → Crash earlier in hung shutdown if we exceed toolkit.asyncshutdown.report_writes_after pref

See https://bugzilla.mozilla.org/show_bug.cgi?id=1610134#c17. This is no longer actionable since the preference will remain at 60s.
