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.
