Just to be clear, there's no danger in running IPv6 or KAME IPSEC in
5.3, you just won't get any benefits from running it on a SMP machine
(neither will you in 5.2.1 or 4.x).

Any problems you observed are presumably orthogonal to the Giant-ness,
so you ideally should report them so they can be analyzed.
