Combining entry_call, accept_statment and terminate_statment

[Lutz Donnerhacke <lutz@iks-jena.de>]

Sorry, but I do not get it:

I have a protected type with an entry:

  protected type PT is
     entry X;
  end PT;
  p : PT;

Now I have to construct a task dealing with new data from the protected
type, an call from other tasks or the termination of the parent task.
  task type TT is
     entry Config;
  end TT;
  
  task body TT is
  begin
     loop
        select
	   p.X;
	   -- dealing with new data
	or accept Config;
	   -- modify the task
	or terminate;
	end select;
     end loop;
  end TT;

Unfortunly this is not allowed. Either accept and terminate or an entry_call
and a delay can be combinded. I wonder how to solve such as deadlock. It
should be a common idiom, but I had no luck in choosing searching keywords.

Any hint?
