Yes, I'm working against upstream. I did check briefly that the code 
hadn't changed too much since 1.3.4 in that area.

I've found one other place that has insufficient locking but the race to 
hit it is fairly small. It's in the Kerberos machine principal cache 
when it refreshes the machine credentials. I have a patch for that, but 
it's pretty invasive due to some other changes I'm currently working on. 
Let me know if you hit it, and I can work on a simple version to backport.

Doug
