Hi Seth,

Yes, I have a pcap containing the ALTER_CONTEXT req/resp packets.  I will start working on the bug fix and submit to BIT, with pcap and test script, hopefully soon.

Thanks Mark!  Those were probably my comments.  Unfortunately there were 
a number of areas where I just ran out of steam doing investigations 
into why things were happening the way they were so this investigation 
is deeply appreciated.

Do you have PCAPs with ALTER_CONTEXT messages in them?  Because this is 
difficult-to-understand change without seeing actual traffic it would be 
best if you were able to submit the changes along with tests.
