OK, and thanks. I wasn't sure which was preferable.

I've done that. I'm not sure whether you expect that to fix the 
'data stale' error or whether it's for debugging purposes. I'm 
still getting the error after running with the above code change.

Again, thanks for your help. And I've subscribed to the dev 
list. Also, I'm quite knowledgeable about userland stuff in OSX, 
but with kernel/driver stuff I will need to follow someone 
else's lead.

So, what else can I do help identify the cause of the error?
