As far as I know the only slow down is when there is actual text
decoding going on, ie not for ByteString I/O.
Simon has promised to explain all in his upcoming talk at the Haskell
Implementers' Workshop. :-)
That will also be the obvious time to discuss what a new public I/O
interface might look like. There's lots of fun new machinery in GHC's
I/O system but we need to talk about public APIs.
