Because of "po = ip_kotype(pager)", and we have a kotype for proxy objects,
so the "if (po != IKOT_NONE) break;" hits ("bail if there is already a
kobject associated with the pager port").  Later below, it is careful to
only do stuff if it is really a VM object, which it isn't because it is an
unhandled kernel object type.

Thanks,
