DNS Update (Thread?)

[Kevin C Miller]

I'm trying to look at what kind of delays our servers are experiencing, and 
how we can improve performance. One of my areas of inquiry has been into 
the DNS Update code; my understanding is that updates block the server 
while waiting for a response/timeout.

So, the first questions is whether this is correct. Secondly, assuming it 
is, does it make sense to try and develop some update code that uses the 
server's existing timeout model to not completely block when doing the 
updates?
