PF Issue with BETA4

It seems that, at least with the PF devices built into the kernel that 
an issue arises during shutdown.  As I was rebooting the server, I 
noticed that the disks were syncing and yet there was a huge amount of 
traffic on my router to the Internet.  Upon inspection, packets were 
still passing through the kernel and a large download was still going on 
through a kernel that should have long ago quite passing traffic!  In 
other words, it appears that the NAT function of PF does not shutdown as 
it should while the the OS is shutting down.  Traffic ceases almost 
immediately with IPFW and IPFILTER.

Thanks,
