    This object essentially provides a more convenient interface around
    :class:`select.poll`.

        ``events`` is a list of ``(fd, event)`` pairs, where ``fd`` is a file
        descriptor or file object and ``event`` either ``'r'`` or ``'w'``.  If
        ``r``, listen for whether that is ready to be read.  If ``w``, listen
        for whether the channel is ready to be written to.

        ``timeout`` is an integer specifying how long to wait for events (in
        milliseconds).  If omitted, ``None`` or negative, wait until an event
        occurs.

        Return a list of all events that occurred before ``timeout``, where
        each event is a pair ``(fd, event)``. ``fd`` is the integral file
        descriptor, and ``event`` a string indicating the event type.  If
        ``'r'``, there is data to read from ``fd``.  If ``'w'``, ``fd`` is
        writable without blocking now.  If ``'h'``, the file descriptor was
        hung up (i.e. the remote side of a pipe was closed).
