The parent will get a SIGCHLD when the child gets SIGSTOP or SIGCONT.
Using sigaction, you can learn which process was affected, and in what
way. We don't have a sigaction wrapper that provides this
functionality, though (the stdlib signal.signal actually wraps
sigaction, but it doesn't expose any more functionality than you get
from signal(2)).
