Further to this, I've not bothered enabling/mounting SWAP space on any of
my systems for the past 4-5 years now, since all of them have 2GB or more RAM.

The world hasn't ended, and my systems continue to work just fine without it,
including the mythtv systems.

Remember, not that long ago, the "advice" was to have as much SWAP as RAM,
and systems typically had only 512MB -> 1GB of RAM.  So add that much SWAP
to the RAM number, and you get.. 1GB-2GB total.

Rather than bothering with SWAP, I just prefer to get the same 2GB total
by using real RAM.
