How many userland processes have to be running and consuming memory which
isn't available as physical RAM at this point in the shutdown sequence?

Wouldn't a loop like the following be enough?
  while swap
      umount unbusy-FS
      swap-off swap

This assumes that swap-off doesn't turns off the swap if it isn't able to put
everything back into other swap or physical RAM areas.

Bye,
Alexander.
