How very strange. Since driver verifier didn't hit any bug checks, I 
spent some more time trying to reproduce this issue without any luck. 
First I sent gobs of fragmented packets through the filter driver and 
then sent gobs of bit torrent traffic through the filter driver. No 
issues whatsoever. Unfortunately, we are down to a brute force process 
of elimination to figure out where this problem is.

When the VPN client is inactive, the filter does almost nothing in the 
NDIS send and receive paths. These three builds incrementally disable 
what little code is being executed. It is important that you try all 
three and let me know if the issue is reproducible with each. With any 
luck, we will only have to try a few more before we find a fix.

NOTE: The VPN client will not function properly with any of these builds 
installed. They are only intended for driver testing.
