'reset' MIDIClient.init on Linux

Questions
1

When you run MIDIClient.init; on Linux you get the Midi sources. But if you run it twice, you’ll get the Midi sources twice in both the Supercollider postwindow as well as in the Midi tab of Qjackctl/JACK.

Is there a way to clean this up, so you are able to have just the Midi sources displayed once again?

It looks like you can use

MIDIClient.init(numIns,numOuts);
MIDIClient.init(6, 6); (for example)
