Given the current price of disk, there is no sane reason not to have
enough swap space configured to make this not-a-problem. The OOM kill
mechanism was a reasonable solution for running systems that were not
expected to be too reliable anyway on small hardware, but if you're
trying to run a 24/7 server you're simply incompetent if you don't
disable it.
