The issue here is the order in which the library makes calls to
hSetBuffering and system("stty icanon echo") to reset the terminal.
For ghc-6, they are in the wrong order, although for nhc98 and ghc-5,
the order doesn't matter.  Hence, a simple fix is to swap these calls
over, as I have just done in CVS.
