Wow, thanks for this perfect description how this is working.

For my part, I am updating  since many years regularly the ports. Never
stop any daemon before.
But after the upgrade I restart the daemon if it is something like
apache, clamav, some milters, mysql.
It never causes trouble. The only thing that if I use restart, rc says
the daemon is not running (but running fine) .
But after reading Your article it is now clear why.
