Shoot, it barely took 10 minutes for me to move the behavior field from
the object to the vm map entry.
I'm testing it now along with the madvise(... MADV_DONTNEED) changes (to
make them work on files in a reasonable way).
This will be current-only, though I suppose the map changes could be
backported to stable if someone really wanted to.
