This behaves exactly like the original method, but in case the
process has ended already and sent us a SIGCHLD, it doesn't wait
for the stdin/stdout pipes to close, because the child process
itself might have passed them to its own child processes.
@note: Twisted 8.2 now has a processExited hook that could
be used in place of this workaround.
