I previously tried using Python blocks (not specifically for this purpose) and found them unusable because combining Python blocks with flow graph reconfiguration (lock()/connect()/unlock() cycle) would cause deadlocks. I just wrote up a simple test script and found that this did not reoccur, but it is under much simpler conditions. (I am currently testing with gnuradio revision ad641c67c18a53a1bb577fad5d5183988aaf19c0 via MacPorts.) I will experiment and see if it is stable when used as a queue replacement.
