Section 9.5.1[1] states:
   "protected functions provide concurrent read-only access to the data." (in
the P.O.)

and

Section 9.5.1[4] states:
   "A new protected action is not started on a protected object while another
   protected action on the same protected object is underway, unless both
   actions are the result of a call on a protected function"

so multiple tasks may be in the same (or multiple) protected function(s) from
the
same P.O. at the same time, correct?
