This one also needs to switch to line buffering. Add/Change:

import System.IO(stdout, hSetBuffering, BufferMode(LineBuffering)) main = hSetBuffering stdout LineBuffering >> f

Thanks a lot, now it does work! This means just the proc1 program has to be changed and everything will work properly (hopefully - at least the haskell part works :) ).
