i think i sort of managed to get the bottom ready:

- pd serves a set of control (swaptask, return, error) and pd/setup
  methods (send, make-outlet, ...)

- pd asks pf to do context switching (pd-enter pd-leave)

result is most intelligence can be written in pf, without pd object
depending too much on C interface. also: all pd data is shielded from
pf, because pf has no control about extent of objects.
