I don't have an environment to test the very latest code, but I'm
pretty sure that the problem you described doesn't exist in the
current by code inspection of netinet6/in6_pcb.c, rev 1.94.  I also
tried NetBSD 3.1 and didn't see the problem.  Could you be more
specific about with which version of the kernel you experienced it?
