somehow, 'real' unix has neither a OOMkiller nor does it flat out die
under heavy loads, it just degrades gracefully. I've seen Solaris and
AIX and BSD servers happily chugging along with load factors in the
100s, significant portions of memory paging, etc, without completely
crumbling to a halt. Soimetimes I wonder why Linux even pretends to
support virtual memory, as you sure don't want it to be paging.
