Well, that used to be the rule of thumb for a Linux-specific problem
with swap space. Today, you can run without swap without a problem.
I keep a gig of swap on hand to avoid out of memory problems at all
costs and have never hit that.
A sane default today would be to set your swap size to at least the
size of your current physical memory. I suggest using a swap space
equivilent to the maximum amount of memory your board can support,
though this is generally considered massive overkill given how cheap
RAM is these days.
