Do resource limits apply to root?

I wonder if it's an issue of calculation in top; top might be including
page sizes and other VM-related things, while limits datasize and stacksize
may only be specific to those allocated amounts.

If this machine was running RELENG_7 (STABLE), it would have procstat,
which could help discern where the "extra" memory is.

Also: is this i386 or amd64?
