[PyQt] pausing and resuming QThread tasks

Hi all,

What's the best way to pause and resume processing in QThread objects?

I've built a small test app that sets up a Python os.walk() process  
that I'd like to be able to pause and restart from where it left off.   
The documentation on QWaitCondition looks promising, though my app  
appears to hang on this line (line 69):


Also, in testing for a paused job in my processing method (line 104),  
does a waiting thread resume from where it left off?  Or do I need to  
keep track of where it is myself and restart it from there?

Thanks in advance!
