# Test inferior resumption after discarding a hand-called function.

# There are two things to test.

# 1) Inferior stops normally.  Upon resumption it should continue normally,

#    regardless of whatever signal the hand-called function got.

# 2) Inferior is stopped at a signal.  Upon resumption it should continue

#    with that signal, regardless of whatever the hand-called function did.
