Details

I though I was seeing a Gecko hang but turns out I was linking libxul.so and had ~10MB of ram free. We should detect this condition so we can easily weed out swapping performance bug. What's the best way to know we're swapping and can we quantify it?
This is a very specific case of the other bug that I've filed about detecting when our thread can be scheduled. I don't think this specific case is worth fixing before that.

Actually I've been looking at the API and it doesn't look like bug 791357 will get us there. There API are uncertain at this point. While tagging a profile with available memory is possible.
