Not speaking specifically for MacPython, but in practice flush is 
usually expected to be there for stdout (don't often see people flush 
stderr)..  it doesn't actually have to do anything if the meaning 
doesn't make sense for your file-like object, but probably should be a 
callable attribute (for example: "sys.stdout.flush = lambda *x:None").
