Last Friday I proposed creating larval SAs to act as
placeholders to prevent a second acquire resulting in 
double SAs being created. 
I tried this and so far I have not seen any double SAs
being created. I also plan to run some stress tests over 
the weekend.

Please let me know what improvements I can make to this patch or
if there is a better way to do this.

I'll take a look at your patch after I deal with some ipv6
locking bugs, thanks Joy.
