just pass signal number to the handler you installs :)

        installHandler sigPIPE Ignore Nothing
        flip mapM_ [sigINT, sigHUP, sigABRT, sigTERM] $ \sig -> do
          installHandler sig handler Nothing
              where handler = Catch $ exitWith (ExitFailure 1)

replace for example last line with

              where handler = Catch $ exitWith (ExitFailure sig)
