It's deliberate, but (AFAIK) not for those reasons. The idea is so that "simple, stupid programs" do what the programmer expects (and saving the list from lots of "my program doesn't get any input until the user hits Return" questions).
If you were writing "stty" in Haskell, you would presumably use the PosixTTY functions directly.
GHC 6.2 will have slightly better behaviour in this regard. If the terminal settings are changed as a result of hSetBuffering, then they will be restored on exit. This still allows stty-type programs to be written, as long as you don't also call hSetBuffering on the same Handle.
Yay! That seems like precisely the right thing to do. :) -- David Roundy http://civet.berkeley.edu/droundy/
