Comment (by alexbiehl):

 Winter this is interesting. As you have setup the benchmark already. Could
 you provide a heap profile for ghc MIO? It would be interesting where the
 massive allocation come from. I think a simple +RTS -hT -RTS should
 suffice (no need to compile with -fprof, thanks Herbert for the tip).
