I don't think this changes the default for anything in 6.x. He changed the
default for his patch from yesterday that made it assume a type if you do
'mdconfig -s <size>'. Currently you have to do:
'mdconfig -a -t malloc -s <size>' or 'mdconfig -a -t swap -s <size>'
but Nick changed it so just '-s <size>' implied '-a -t malloc', and now
he's changed it to imply '-a -t swap'.
