I've had u-area swapping turned off almost from day-1 in DragonFly
with no adverse effects. I'm still using the area for a stack so
I haven't completely ripped it out, but as far as the swapping goes
I think it's a good idea to rip it out. It does significantly simplify
certain aspects of the kernel.
