Hmm, normally when over-commit is turned off, malloc will return NULL,
but when turned on (default on most systems), _some_ process will be
killed when you run out of memory.  The process receiving SIGKILL is
somehow evaluated to be a memory offender by the operating system, but
may not be the process "responsible".
