The following patch fixes this problem for me. When a tcp6 was
encountered then v6bind is set to 1 and was not being cleared
after the check to ignore IPv6. This patch may not be entirely
correct, but its simple and does fix the problem I reported
earlier. The v4bind check that should have resulted in clearing
v6bind back to 0 seems a bit questionable. I believe the flag
should be cleared always.
