So the goal here is that we get OOM data where processes survive long enough
send telemetry. To get the case where processes -crash- we'll also have to
get crash data. See Bug 1964092 for that half.

I'm requesting backout for this and will re-land an updated version that is hopefully safer after soft-freeze.
