I guess this is right (sorry, haven't checked). You can flush in
two ways (using module IO):

1. At the beginning:
       hSetBuffering stdout LineBuffering
   or even
       hSetBuffering stdout NoBuffering
   (the latter slows down the I/O).

2. After each write to be flushed:
       hFlush stdout

stdout is either line buffered or block buffered by default, depending
on whether it's a terminal or not.
