This is fixed in r6668 but I've made it match CPython's behavior. That 
differs from 2.2 on POSIX. What's now returned is the status code which 
needs to be passed through os.WEXITSTATUS.

Though after doing this I'm wondering if we should bother with that 
different status code, as our current os.system doesn't do this either 
(but does on CPython)
