While merging your pull request I noticed that the
`SocketTextStreamFunction` actually does not wait the time specified in
`CONNCTION_RETRY_SLEEP` but immediately tries to reconnect in case of an EOF.
It only waits in case of a `ConnectionError`. I'm not sure whether this
behavior is desired but this should also be reflected in your test cases. Could
you add a test case where you first pass a Socket with an EOF and then let an
`ConnectionError` occur?
