Well, I hope this is the final version.

I added a patch for FreeBSD 6 but i'am not able to test it.

On 7-STABLE, I've tested with hundred openssl encryptions and some flood
pings under ipsec in the background. Looks good for me.

If someone can test and review it, it would be cool.

Thanks, Regards.
