Actually, I'm pretty sure that most Haskell RTS implementations have a
finalizer attached to all file handles. Once the file handle is no
longer reachable from the program graph (even if its data has not been
fully consumed), the GC will close the file (via the finalizer) before
reaping the memory associated with the handle.
