    Problem Text
    This test calls a non-async-safe function (pthread_exit) in an
    asynchronously cancellable thread.

    The test creates a child thread. The child thread changes its
    cancellability type to asynchronous. After cancelling itself
    it calls pthread_exit, which is not an async-safe function.
    Calling a non-async-safe function with async-cancellation
    enabled might have enexpected consequences.

    There is no reason to call pthread-exit in this test, except
    to pass a value back to the parent thread. This call can be
    removed without affecting the the way the test functions with
    respect to testing the assertion.
