Nokia Lumia 920 sensitive screen might be a battery hog the way Windows Phone manages touch

The guys over at JDB Pocketware are worried that this feature might cause unacceptable battery drain the way Windows Phone is structured right now. When you press the lock/power button or the dedicated camera key, and then touch on the screen, the standby sequence reboots each time, even if the proximity sensor tells it there is something very nearby.
We were also wondering about what happens if the power key gets pressed by accident in your pocket, and whether the phone might slide up the lock screen and start chaotically running apps or dialing numbers, but we are sure Nokia has given this some thought way before us, too. Still, we intend to test the bejeezus out of the Lumia 920's pocket behavior in our review.
Is the super-sensitive Lumia 920 screen taking from your sleep at night, or do you think Nokia has thought QAed this and taken measures way before all of us started to worry?
