Your "gsi> " is buffered because there's no newline at the end.
To flush the buffer and force it to be printed immediately, use
'hFlush' from the System.IO library, or use 'hSetBuffering' from
that same library: http://haskell.org/ghc/docs/latest/html/

I believe you can observe the same behavior in C.
Most C stdio libraries in my experience have extra code in the
functions that read stdin to flush stdout first, specifically
because of lazy people who don't pay attention to buffering.
Why can't GHC implement the same thing?
