Due to bug 821502 [1], if you build Firefox 18 for Linux/Android with
GCC 4.4 (and perhaps earlier), GCC will miscompile the JS engine.
These miscompilations are known to cause test failures [2] and crashes

I just sent a message to dev-privacy to discuss partial third-party

Of course, I imagine your goal is not to pull in pages in RAM for
these zero pages. I suspect mmap may do what you want on Linux and
Mac, so long as you don't write to the pages.
Yes, all zeroed pages are mapped to the same physical page under Linux.
