In their pcap, the repeated re-register (about every second after 105) was 
matching my own replicated test results, even though I had to reduce the expiry 
to 30 seconds to get there.  This is definitely fixing that portion at least of 
the issue, but I will go ahead and send them a patch and ask them to check 
their results. 

And they responded:

---------------------------------------------

Tested for 20 hours on latest 11-SVN, problem is gone. Thanks!
I suggest more testing by 2-3 others, though, before commit.
