This is not all that surprising, since there's a bunch of TLB
invalidation overhead needed in the single-process-mfs case which
isn't needed in the current scheme..

it's not the context switch overhead, it's merely improper
accounting.. a lot of the work you're causing happens in the mount_mfs
process, but bonnie doesn't know that..
