     If you wish to get the exit status of the child you must call the
-    close() method. The exit or signal status of the child will be stored
-    in self.exitstatus or self.signalstatus. If the child exited normally
-    then exitstatus will store the exit return code and signalstatus will
-    be None. If the child was terminated abnormally with a signal then
-    signalstatus will store the signal value and exitstatus will be None.
-    If you need more detail you can also read the self.status member which
-    stores the status returned by os.waitpid. You can interpret this using
-    os.WIFEXITED/os.WEXITSTATUS or os.WIFSIGNALED/os.TERMSIG. """
