The problem with having them created on demand is that the time you
need swap is probably _not_ the time you want a daemon firing up to
create it.
Well it'd either be an always running little daemon or whatever's
triggering it needs to be more forward thinking that at the last
minute. I have no idea how macOS's swap files mechanism works exactly
but it creates swap files on demand.
