Comment (by simonmar):

 I'd advise against this.  forking is a total pain in a multi-threaded
 program, and I really don't want to commit to making it work for anything
 other than simple fork/exec type usage (and possibly not even that - doing
 the fork/exec in C is better).

 Do you really need both -threaded and `forkProcess`?  Can you fork in C
 ''before'' starting up the Haskell runtime?
