1594015 - Don't give large event delay numbers for threads that wait outside of ProcessNextEvent

Status: RESOLVED FIXED

(Core :: Performance: General, defect, P2)

Description

[Randell Jesup [:jesup] (needinfo me)]

DOM Worker threads and Socket Thread have custom event loops that wait for events outside of ProcessNextEvent; this can lead to spurious long event delay numbers from bug 1572337 for these threads, especially at thread startup.

Attachment: Bug 1594015: Ensure that threads with odd ProcessNextEvent loops get correct event delays r=froydnj

Socket Thread and Worker Threads use custom event loops and don't wait in
calls to ProcessNextEvent all the time; this can lead to odd Responsiveness numbers.

Depends on D41637
