Then put more effort into debugging your daemon so it doesn't have
bugs that make it die?  Implement the timeout in a robust independent
daemon if it's other code there that's unreliable?

In what way are your requirements so different that a locked-into-memory
monitoring daemon cannot implement this timeout?
