1560948 - Workers repeatedly GC and CC during an ongoing low memory state

Status: RESOLVED FIXED

(Core :: DOM: Workers, task, P3)

Description

[Jon Coppeard (:jonco)]

For the main runtime we only do this once when we enter the low memory state:

This check doesn't exist for workers and so low-memory-ongoing notifications will also trigger GC and CC.

Ignore ongoing memory pressure events on workers like we do on the main thread.
