Comment (by bennofs):

 I'm not using the threaded runtime. I think this is more difficult than
 just closing the .hp file. Wouldn't it make sense that the current cost
 centre stack is discarded in the child process, such that it behaves just
 like if the `IO` action passed to `forkProcess` was `main` ?
