If people are paranoid about swap I can think of some simple
1) configure kernel not to dump
   (though debugging would be *fun* ;-) )
2) scrub the partition (many methods) swap is on, then run mkswap on
   the partition during shutdown (never tried this with swap,
   but have done so on normal fs scratch partitions)
3) don't use swap, ram is cheap ;-)
