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)).
