No.

Either "timeout" or "" would be fine here.  Unless the
connection is closed, in which case you should receive the
notification.  My choice seems consistent with the behavior
below.

I think this is standard behavior. When and if new data
arrives, it will return you the empty string. Or when the
connection is closed, it will also let you know.
