runghc leaks space in IO

runghc mysteriously uses memory to perform IO.

main = forever $ return ()
main = sequence_ $ repeat $ return ()
main = mapM_ print [0..]
-- et al.

I have encountered this bug with 7.4.2 on Windows and linux, and 7.6.1 on linux.

This only seems to happen with runghc, not with ghci or ghc -e.

I don't know what Component contains runghc, so I have left it blank for now.
