To followup on comment 44, with the tooling and tests added via bug 1727571, bug 1539518, bug 1727837, I think I narrowed down the parent process leak. So I hope to fix this parent process issue and only have improvement coming from bug 1702715.

So I hope to fix this parent process issue and only have improvement coming from bug 1702715. Bug 1727839 and bug 1727838 are the two underlying issue which cause the parent process leak.
