1689182 - Collect resident unique set size for MemoryTelemetry from the parent process

Status: RESOLVED FIXED

(Core :: XPCOM, enhancement)

Description

[Nika Layzell [:nika] (ooo, ni? for response)]

We're currently waking each content process, including preallocated ones which should be idle, on a regular basis due to the parent process asking it to collect its current resident unique set size. This is possible to do from the parent process without waking content since bug 1652813. See bug 1689164 for more details.

Note that we'll want to be sure to do this from a background thread, since these computations can sometimes be pretty slow and expensive.
