Consider the following two-process synchronization solution. Process 0 - - - - - - - - Entry: loop while (turn == 1);  (critical section) Exit: turn = 1; Process 1 - - - - - - - - Entry: loop while (turn == 0);  (critical section) Exit: turn = 0;   The shared variable turn is initialized to zero. Which one of the following is TRUE?
