This is a ridiculous limit since genfs currently panics with pagecount
of over 16.  You could unify the magic onstack constant with genfs
so that we don't have random constants all over the place.  Also, you
could shortcircuit the allocation so that you don't always unnecessarily
allocate for unapplicable faults such as read faults.
