The GHC Haskell library makes some compromises with normal I/O
functionality for the sake of its runtime thread system.  As
difficult as named pipes can be in any case, they can be even
trickier in GHC Haskell for this reason.  I didn't suggest an
FFI approach myself, in my previous follow-up, only because
if you haven't worked with the FFI it's a significant initial
investment, but I believe it's what I would do.  (If I were
somehow compelled to used named pipes.)
