[PATCH 0/2] selftests/mm: fix deadlock after pthread_create

[Edward Liaw <edliaw@google.com>]

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.

Updated the synchronization primitive to use pthread_barrier instead of
atomic_bool.

Applied the same fix to the wp-fork-with-event test.
