2228,runghc screws up terminal buffering mode and doesn't reset it,guest,igloo,"If I use runghc to run a Haskell script that reads from stdin, my terminal gets put into a strange buffering mode.  This makes the script essentially unusable: characters are echoed twice, and Backspace and EOF don't work.  The state is not even reset afterwards, so future non-Haskell programs act strangely as well.

There is no problem if the script is compiled with ghc instead of interpreted with runghc.
