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
