16 | # Test inferior resumption after discarding a hand-called function. | |
17 | # There are two things to test. | |
18 | # 1) Inferior stops normally. Upon resumption it should continue normally, | |
19 | # regardless of whatever signal the hand-called function got. | |
20 | # 2) Inferior is stopped at a signal. Upon resumption it should continue | |
21 | # with that signal, regardless of whatever the hand-called function did. | |
