The rule of thumb is to put twice as much swap in as you have
real memory, but I have found from experience that putting four times
the swap as real memory is better... I can often fill up a 2x swap
long before the machine would otherwise thrash itself to death. Also,
running out of memory+swap is a very bad thing, so you definitely want
to err on the side of caution and put more swap in then you think you
need.
