In GNU Radio 3.7.6 this is still an issue. It's quite serious because whole class of applications that would use message passing and rely on the processing in the flowgraph to end after processing of chunk of the signal (i.e. to change the flowgraph in known conditions) is not possible. I'm working on a simple gsm network monitor application based on gr-gsm (https://github.com/ptrkrysik/gr-gsm) and have quite hard time because of this issue. Is this some general problem where the source of it is that GNU Radio was meant primarily to process stream of samples? Or is it some simpler matter? I've attached vary simple flowgraph that demonstrates the problem. Best Regards, Piotr Krysik
