(Whiteboard: [MemShrink:P2])

I could have sworn the threshold had already been reduced to 0, but it appears not! Hopefully we can reduce it without too much trouble.
I did a try push with the leak threshold reduced to 8, on Linux and Windows:

There's a permaleak in dom/base, at least on Linux and Linux64. This looks the same as bug 1189646.

There's some kind of leak only on Windows, in most mochitests:
TEST-UNEXPECTED-FAIL | leakcheck | tab process: 12 bytes leaked (nsStringBuffer, nsTArray_base)

This was a push without bug 1401412, so it is possible that 12 byte leak is the same thing, just slightly bigger on Windows. But I do see it on recent treeherder pushes, so I'm guessing it is different. Digging into the Windows failures isn't worthwhile until I have a push with the threshold increased to 12 to avoid this.
