+# mutually exclusive, i.e., that when $_exitsignal is set, $_exitcode
+# is not, and vice-versa.  This mutual exclusion happens because if an
+# inferior exited (either successfuly or not), it certainly was not
+# killed by a signal.  However, if it was killed by an uncaught
+# signal, then there is no way for it to have exited.
