 Congratulations !
 I tested TB run twice for 5 min and all is clean (no process left behind).
 This is strange, as I have run these firewall rules for ages, and also
 have been using TB weekly for a couple of years. Only very recently (prior
 to New Year) this problem popped up.
 This would indicate that my original iptables rules order started blocking
 something INVALID very recently - problem in TB or in iptables (most
 recent upgrade was 2018-11-28 1:1.8.0-1 -> 1:1.8.2-1).
