[Swan-dev] unstable connection serial numbers

[Andrew Cagney]

I'm trying to understand this diff
https://testing.libreswan.org/v3.30-1853-gc4b35c42cb-main/newoe-25-cat-2/OUTPUT/road.console.diff

-000 "block":   newest ISAKMP SA: #0; newest IPsec SA: #0; conn serial: $9;
+000 "block":   newest ISAKMP SA: #0; newest IPsec SA: #0; conn serial: $5;

Pluto is receiving something like the following from whack:

- add $1 clear
- add $2 clear-or-private
- add $3 private-or-clear
- add $4 private

but then it receives either:

- add $5 block
- listen -> triggers groups $6-$9

or:

- listen-> triggers groups $5-$8
- add $9 block

I'm guessing there are two whacks or something?
