# purpose of this checking is to ensure that the variables are
|
|
# 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.
