Actually I have seen the same error message from a f.flush() before,
so I already had coded:

   try: 
      f.flush()
   except IOError:
      pass

But maybe I should repeat the flush() until it succeeds, and only
then close() the file. Since I wrote my first message I have already
found occasions where even the sleep(0.1) doesn't solve the problem.
Bad. I really hope I can properly fix this.
