On Android arm, pthread_create followed by a fork caused a deadlock in the case where the fork required work to be completed by the created thread.
The previous patches incorrectly assumed that the parent would always initialize the pthread_barrier for the child thread. This reverts the change and replaces the fix for wp-fork-with-event with the original use of atomic_bool.
