OSC messages that fall within a block override each other failing DoneActions

[telephon]

This has been a long standing issue, but I'd like to put a good reproducer here. It has to do with how DoneActions in the server are handled, or rather when they are called. Because when controls are set within one block size, the appropriate action may never be performed.

As we all know, this may cause hanging noses.

// run a silent synth
a = { |gate=1| FreeSelf.kr(1 - gate) }.play; a.onFree { "synth ended.".postln };
 
// CASE 1 set the gate to 0. This frees the synth.
s.sendBundle(0.2, ["/n_set", a.nodeID, "gate", 0]);


// run a silent synth
a = { |gate=1| FreeSelf.kr(1 - gate) }.play; a.onFree { "synth ended.".postln };

// CASE 2 set the gate to 0, then to 1. This doesn't free the synth.
s.sendBundle(0.2, ["/n_set", a.nodeID, "gate", 0],  ["/n_set", a.nodeID, "gate", 1]);


// run a silent synth
a = { |gate=1| FreeSelf.kr(1 - gate) }.play; a.onFree { "synth ended.".postln };


// CASE 3 set the gate to 0, then to 1, but with 0.1 s time difference. This frees the synth.
(
s.sendBundle(0.2, ["/n_set", a.nodeID, "gate", 0]);
s.sendBundle(0.21, ["/n_set", a.nodeID, "gate", 1]);
)

CASE 2 may happen under the hood where one least expects it.

btw. also this doesn't free:

a = { |gate=1| FreeSelf.kr(1 - gate) }.play; a.onFree { "synth ended.".postln };

(
s.sendBundle(0.2, ["/n_set", a.nodeID, "gate", 0]);
s.sendBundle(0.200001, ["/n_set", a.nodeID, "gate", 1]);
)
