Could you please provide a bit more information about why these are 
necessary and why they weren't there before (or how you figured out that 
there was a problem without them)? I learn a lot by reading commit mail, 
but only when the log message and any added code comments explain the 
"what" *and* the "why".

Cheers,
Lawrence
