David Schultz e92686d065 If we seem to be out of VM, don't allow the pagedaemon to kill
processes in the first pass.  Among other things, this will give
us a chance to launder vnode-backed pages before concluding that
we need more swap.  This is particularly useful for systems that
have no swap.

While here, update a comment and remove some long-unused code.
