17 # purpose of this checking is to ensure that the variables are
18 # mutually exclusive, i.e., that when $_exitsignal is set, $_exitcode
19 # is not, and vice-versa. This mutual exclusion happens because if an
20 # inferior exited (either successfuly or not), it certainly was not
21 # killed by a signal. However, if it was killed by an uncaught
22 # signal, then there is no way for it to have exited.
