It looks to me like this code requires a forkIO, not in the writing to inp, but rather in the reading of out and err. Otherwise, those buffers may fill up and your process will hang...
It seems to be as you say. Trying for a single-threaded solution to this problem always locked up the program, until I found someone's code snippet online using forkIO and extrapolated from that. Sincerely, Rafal Kolanski.
