[Discuss-gnuradio] hanging on top_block.stop

[Ben Reynwar]

Hi all,

The following script hangs for me about 1 time in 10 on the call to
top_block.stop.
Drilling in a bit, it appears to get stuck on a call to 'interrupt' of
a boost::thread instance on line 91 of gruel/src/lib/thread_group.cc.
Has anyone else had this problem?

Cheers,
Ben

    tb.connect(src, snk)
    tb.start()
    time.sleep(0.01)
    print("**********About to Stop***********")
    tb.stop()
    print("**********Stopped***********")
