- ----------
-
- when the child is under trace, all the signals meant for child
- will go to the parent and the child enters stop state.
-
- when you call ptrace with option 7 (resume execution), the
- child will continue execution and the pending signals
- are delivered to the child, which may make the child
- enter stopped state again.
-
- you can explicitly send a signal apart from the pending signal
- to the child by setting the data field to the valid signal
- number. this signal is delivered ahead of the pending signals.
