Ditto. It's a hot running camera. Even the manual warns of
burning your fingers when taking the CF card out!!!!!! It runs
even hotter if you are not using the battery-grip.

I have. On mine, after the first hour the noise floor increases
by at least a factor of about 50%. There it stabilizes and
doesn't get any worse. However, the "hot pixels" start to show
up with vengence.
I let my cameras go to sleep in one minute. This keeps things a
little cooler and extends battery life. If it looks like I'm
going to take a picture I just touch the shutter release to give
it a wake-up call.
Depending on all of your AF settings, the anti-shake mechanism
isn't active unless your finger is actually depressing the
shutter-release to the 1/2 way point. You can hear it operate
and I know in one grip-sensor setting, the A/S is active
whenever you have your hand on the grip.
