One suggestion, one question.

::: toolkit/components/perfmonitoring/tests/browser/browser_compartments.js:37
(Diff revision 1)
> +let pid = getpid();

Because of the mixture of scopes in this file, pid is getting overloaded and it gets a bit confusing.

Maybe: `const PARENT_PID = getpid();`?

Will this work with sandboxing?

Well, if `getpid`/`GetCurrentProcessId` is blocked by sandboxing, the C++ code will also break, so I'm going to assume that this should work.

Can we run this through Try now so it can land ASAP once it has review? It's blocking a frequent crash in automation :(

For consistency, I have moved the fixup patch to bug 1175098.

Mmmh...
Apparently, my libc call in the test doesn't work on Linux. I'll see what I can do about that.
