My view on this is that Linux overcommits, so the actual likely way that "oops, out of memory" will manifest is by some page not being able to be allocated-on-demand, at which point your process is toast anyway. Checking malloc returns is really only checking your virtual address space allocation, which typically speaking always succeeds, except in the "we tried to get gigabytes at once" case... thanks -- PMM
