[ci skip] Updating docs to reflect actual bulk delete

fix tedious error handling

The previous commit incorrectly invalidated the connection, when we
should really be removing the connection from the pool completely.
This also fixes an error in the disconnect logic, which was erroneously
checking connection.connected to identify an already disconnected
connection.
