I was attempting to debug a program.  I was expecting self._inFlush to execute 
the return at least sometimes but not always.  I then changed the code and 
things started working.  But to my eyes I could determine the difference 
between
if ...:
  return

and 

if not ...:

else:
  return

I still don't!  But for some reason it works!
