Subject: RE: port bound SAs

i did exactly that (in the original message) and it makes this test case
work but as I point out

a) it should not be necessary 
b) i get more SAs than I need
c) i can no longer say that a SA is optional (this is an error in the
pfkey/xfrm/racoon interface to combine two orthogonal concepts)
d) I am not convinced that I have resolved all cases. Needs more testing

Assuming you're also using setkey, try adding "unique" to your policies.
