[Haskell-beginners] Timed Profiling

I believe that timeout sends a kill signal to the process in question. I
imagine that the process is killed before the profiling information is
written and so you get an empty file. When you close the program with
alt-F4, the program gets a chance to shut down cleanly and writes on the
profiling information (.prof)
