* Store the native representation directly in the `ExitStatus` structure instead of a "parsed version" (mostly for Unix). * On Windows, be more robust against processes exiting with the status of 259. Unfortunately this exit code corresponds to `STILL_ACTIVE`, causing libstd to think the process was still alive, causing an infinite loop. Instead the loop is removed altogether and `WaitForSingleObject` is used to wait for the process to exit.
