We have the following small piece of Ada code. If we assume that two Bar messages and two Baz messages have arrived before we reach the top of the loop, how many messages will be processed in a single iteration of the loop?

 task body Foo is
   begin
     loop
       accept Baz(parameters) do
         -- do Baz processing here
       end Baz;
       
       accept Bar(parameters) do
         -- do Bar processing here
       end Bar;
     end loop;
  end Foo;
