Every time we start the child, we rebuild this kqueue from scratch for the child and tear it down before we exit and check if we need to restart the child. As a consequence, we effectively drop any of the signals we're interested in between restarts. Push the kqueue out into the daemon state to avoid losing any signal events in the process, and reimplement the restart timer in terms of kqueue timers. The pipe read event will be automatically deleted upon last close, which leaves us with only the signal events that really get retained between restarts of the child.
