["this" is flushing stdout when we read from stdin, if I have followed
correctly]
Can you please say where the report says this? I've just skimmed
http://haskell.org/onlinereport/io.html
and didn't see it mentioned.
Also, if there's a GHC bug about this, can you please point me to it? A
quick search didn't find anything.

I'm not sure which example you're referring to, but the first example on
the above page
21.10.1 Summing Two Numbers
starts off by doing
hSetBuffering stdout NoBuffering
which implies to me that implementations are not expected to do the
flushing hack.
Thanks
Ian
