Conal [http://thread.gmane.org/gmane.comp.lang.haskell.libraries/15592
reported] that the `Show` instance for `IOCallback` conflicts with the
more general `instance Show (a -> b)` defined in `Text.Show.Functions`.
The attached patch removes the `Show` instance for `IOCallback` like Bryan
propsed. It also removes the `Show` instance for `FdData` since that type
contains an `IOCallback`. I don't think this matters because `FdData` is
an internal type.
