Thanks for your comments. (I had overlooked "readFile", which certainly looks safer.
It isn't:
readFile :: FilePath -> IO String readFile name = openFile name ReadMode >>= hGetContents
Why does not hGetContents set a flag associated to the handle. The flag is turned off if no lazy io thru the handle can happen. hClose checks the flag and eventually passes the close to the OS if no flag is set anymore.
