    Return a list of InotifyEvent instances representing events read from
    inotify.  If timeout is None, this will block forever until at least one
    event can be read.  Otherwise, timeout should be an integer or float
    specifying a timeout in seconds.  If get_events times out waiting for
    events, an empty list will be returned.  If timeout is zero, get_events
    will not block.
    This version of get_events() will only block the current greenlet.
