I don't know if I can quantify the issue very well, but since moving 
from 4.4-RELEASE to 4.5-RELEASE on my laptop, I've noticed that 
TCP-over-IPv6 sessions get stuck rather easily. They end up in a state 
where no further I/O will take place. TCP-over-IPv4 does not have this 
problem.

This machine is using IPSEC over 802.11b (wi0 - a lucent gold card), and 
a (gif0) tunnel for IPv6-over-v4 (without any IPSEC since it's tunneling 
over v4 which is IPSECed anyway).

Can anyone think of a reason why 4.5-RELEASE should be having problems 
in this area that 4.4-RELEASE did not?
