def tasklet(func):
    """Tasklet decorator that lets the caller specify either async or sync
    behavior at runtime.

    If make_sync is False (the default), the tasklet returns a future and
    can be used in asynchronous control flow from within other tasklets
    (like ndb.tasklet). If make_sync is True, the tasklet will wait for its
    results and return them, allowing you to call the tasklet from synchronous
