  * Rewrite the documentation for forkOS again
  Try to make it clearer that forkOS is only necessary when calling
  foreing libraries that use thread-local state, and it has nothing to
  do with scheduling behaviour between Haskell threads.  I also added
  something about the performance impact of forkOS, and mentioned that
  the main thread is a bound thread.

    M ./Control/Concurrent.hs -20 +31
