What if you know: 1) You are on a memory overcommit architecture. 2) You know that if you run out of swap for dirty pages, whoever asks for a page at that point will be killed with sig 11 because there is no memory left. 3) You are providing a system critical service, so you don't want to die because you were too stupid to preallocate pages. ?
