I wrote a program. It starts a process (call it A) that spawns a child process (call it D) that shutdowns and restarts A. Problem is, now I can't kill A nicely from the terminal (ie. CTRL-C isn't getting to it). The pgid's of A and D are the same, but it looks like the terminal drops that process group as its foreground, which is why I can't send it signals now. I suspect this happens when the parent process originally dies. Is there some way to prevent that? Can I change the foreground pgid so it looks like the child (D) is actually the parent and the terminal doesn't drop the process group?

Parent restarted by child doesn't respond to CTRL-C
