I wanted to test your python file.
I first commented out the lock/unlock and the program continuously
prints "noflow". Is this the expected behavior?

My understainding is that after every flushing of the message queue and
sleeping of 1 msec, the message queue should always be non-empty
(samples have been produced and are continuously produced at the
maximum possible rate (based on the CPU) by the source block).
BTW, the sampling rate of 8MHz is meaningless in this graph, right?

Also, when i change the sleeping to 10msec then the behavior (with
lock/unlock commented out) is as expected.

I know this is not adressing your lock/unlock question, but i thought
we first have to understand the simpler behavior of the graph without
the lock/unlock...

what am i missing?
