Hi again, I forgot to press enter so the issue does happen on my end too:
m@mi7:~/Downloads$ time ./unconnect_test.py -f my_sink: init 36995152 Running until enter is pressed: my_sink: work: 32768 my_sink: work: 32767 my_sink: work: 32768 my_sink: work: 32767 my_sink: work: 32768 my_sink: work: 32767 Setting new sink. my_sink: init 36995472 Unlocking... ^C^Z [1]+ Stopped ./unconnect_test.py -f real 2m45.886s user 0m0.000s sys 0m0.000s I'll have a look into it.
