/**
   Test: VII_case1_ii   - upc_notify test with an expression which does not 
                          contain shared references (same expression). 
   Purpose: to check that no thread may proceed from the upc_wait until
            after all other threads have issued their upc_notify
            statements.
   Type: Positive.
   How : - Declare a shared array, a, of integers of size THREADS. 
           This array will be automatically initialized to 0.
         - Just before reaching the notify statement, each thread will set 
           a[MYTHREAD] to 1.
         - Right after the wait statement, every thread should check that 
           a is filled with ones. Otherwise, the barrier statement is not
           working properly.
