## This appears to be what works. 
    def __exec(self,args) :
        """Run the process with arguments"""
       p = subprocess.Popen(args,stderr=subprocess.PIPE,stdout=subprocess.PIPE)
       while 1 :
           output = p.stdout.read()
           if output :
               print(output)
           else : break
       errmsg = p.communicate()[1]
       if errmsg :
           self.__err('Process terminated with error:',errmsg)
## Thanks again, gnarly one for me. I am eternally a noob!
