Successive calls will update *obj*'s eventmask to the value of
*eventmask* (i.e. will behave as `modify()`).
.. method:: poll.unregister(obj)
Unregister *obj* from polling.
.. method:: poll.modify(obj, eventmask)
Modify the *eventmask* for *obj*.
Modify the *eventmask* for *obj*. If *obj* is not registered, `OSError`
is raised with error of ENOENT.
.. method:: poll.poll(timeout=-1)
