You're hardly the only one.  Some years ago, running Linux web and
database servers, I quit creating swap space.  A runaway program would
turn the system into an infinite game of shuffle-the-pages well before
the OOM killer actually decided to kill something, and in that state,
one couldn't even reboot.  This expanded the time window of "broken"
from tens of seconds, and perhaps a service restart, into tens of
minutes and a power button recovery.  Every #$%^&* time.
