You can run 'top' while executing your flow graph and then toggle
threads on (type capital 'H'). Each thread will be displayed on its
own. With a Python-based GNU Radio application, all you will see is
python; when you toggle threads on, you should see python listed
multiple times; one for each thread.

'man top' will tell you how to get a lot out of that program.
