Hmm, I removed that code by mistake and that broke procps. So I added
it again. Why does it break heap randomisation? I don't know if both
__environ and __curbrk is needed for procps. Maybe only one of
them is needed? Does heap randomisation need both of them to go away
or is it enough with __curbrk?
