hClose on stdin,stdout,stderr now actually closes the file
descriptor.  Before, there was no way to actually close these file
descriptors, which might be necessary in some cases - especially when
stdin/stdout are pipes and you need to indicate to the other end of
the pipe that you've finished I/O, but without exiting the program.
