  * A utility class to handle role requests and replies for this channel.

- *
- * To simplify role handling we only keep track of the /last/ pending
- * role reply send to the switch. If multiple requests are pending and
- * we receive replies for earlier requests we ignore them. However, this
- * way of handling pending requests implies that we could wait forever if
