[Discuss-gnuradio] run a loop within GR

[Jason Matusiak]

I have a python script I built up for GR that runs on my E310.  As part 
of the startup, it checks for a GPS fix and waits until it gets one 
before moving on.  My question is how I can have my script running, yet 
occasionally check for GPS lock so I can do something with knowledge 
(like output that I have lost GPS lock)?  I haven't been able to figure 
out how to have the script run, yet occasionally run a parallel task.  
Is there an example of something like this that someone could point me to?
