// Package panicmon provides a method of spawning processes and monitoring
// its behavior via generic pluggable handlers.
//
// On linux we want to signal to the child process that when its parent dies
// it should die as well via receiving SIGKILL. This is because panicmon is
// set up to forward every signal, so if it dies we assume that means it was
// because it was sent SIGTERM, which it propagated to the child, which the
// child then did not process and shut down in time to prevent the supervisor
// (supervisord / systemd) from sending the parent a SIGKILL, which it cannot
// ignore and thus not pass to child, meaning that the child as well should
// exit as if it was passed SIGKILL.
