Decrements the value of atomic by 1.
Think of this operation as an atomic version of { *atomic -= 1; return (*atomic == 0); }.
This call acts as a full compiler and hardware memory barrier.
While atomic has a volatile qualifier, this is a historical artifact and the pointer passed to it should not be volatile.
