BlockBuffering is worse, not better, and the docs *explicitly* say
that switching to NoBuffering will break ^D (if it wasn't broken
already...) My specification for a working program is `one that
works exactly like every other program on my machine'. I don't see
how to produce such a program with GHC.(1)
(1) Using readline might work (although I'm kind of sceptical given
what's preceded it), but I haven't gotten it to link thus far...
