I am writing a gnu radio application where I started a thread to read an  
external socket. It seemed to introduce some odd behaviours such as  
looping  
back of signal where I did not expect it. Is it permissible to start  
blocking threads in the python part of a gnu radio application?

I am relatively new to gnu radio. If I missed the obvious it would not  
surprise me.

Thank you

Sounds completely fine to me. Many of the gnuradio gui apps are spawning  
threads for various things.

Thanks for the quick reply. Red herring on my part.
