Avail Page File on Windows and fire a memory-pressure event when it gets low
MEMORYSTATUSEX.ullAvailPageFile tells us how much space is available in physical memory plus the page file. When this gets to 0, Windows will not let us map any more memory. So we should raise a low-memory event before we get here.
See also bug 720444, where we added ullAvailPageFile to crash reports.

Summary: Monitor ullAvailPageFile on Windows and fire a low-memory event when it gets low → Monitor ullAvailPageFile on Windows and fire a memory-pressure event when it gets low
I need to add a line to telemetryping.js to send this memory reporter.

I think this might be covered elsewhere, but I can't find it. Why is the checking for low physical, commit and virtual memory Windows-only?
(In reply to Daniel Cater from comment #8) > I think this might be covered elsewhere, but I can't find it. Why is the > checking for low physical, commit and virtual memory Windows-only? Because it's hard(er) to do elsewhere, and because it's not a clear win on Windows, so we wanted to do it there before wasting our time elsewhere. Also, Windows machines are much more likely to be running a 32-bit Firefox than Mac or Linux. https://bugzilla.mozilla.org/show_bug.cgi?id=664291
