Hi Elias,

Testing the queue handling stuff without actually issuing any

used to freeze the queue after command completion which I'd really
like to test. If I don't issue any command, I don't know how to test
whether the callback procedure and all the rest works as expected.

Try doing a dump_stack(), and nothing else, in the callback. This may
provide some hint.

(Remember to increase console_loglevel so you can see the result on
the console before the hang.)
