5092	Remove Show instance for GHC.Event.IOCallback	basvandijk	igloo	"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."	feature request	closed	normal		libraries/base	7.0.3	fixed			Unknown/Multiple	Unknown/Multiple	None/Unknown
