It's a no-op, thus it can be sent when you just want to send some message:
* The Abandon request has no reponse.
* rfc4511 §4.11: "Servers MUST discard Abandon requests for messageIDs
they do not recognize, for operations that cannot be abandoned, (...)
* No request may have Message ID 0 (§22.214.171.124); 0 is reserved for
Unsolicited Notifications. Yet Message IDs are just defined as
0..2^^31-1, so abandon(0) is not a protocolError.
Thus abandon(0) is a no-op.
I can imagine some implementation treating it as protocolError anyway
though. It's not as if everyone agrees what the letter of the standard
means, and follow it to the letter.
