General :: Disable Screen Auto Wake In Android

I have a specific problem that has persisted through multiple android devices, through all ROMs and builds. Currently I am on a Verizon galaxy nexus with cyanogen 10.1 (background in case it's more relevant than I believe).

When a timer or alarm goes off on my device, or when I receive a call or text, my screen wakes automatically. I think this may be considered a "feature" in android. However, since my phone is nearly always in my pocket, it means that the screen turns on and often receives enough of a false signal in my pocket to disable an alarm or decline/accept a call. It is very inconvenient and would be alleviated if I could specify that I want my device to turn on the screen ONLY when I press the power button.

I know that others have the same problem from searches on xda and elsewhere, but I don't see solutions (except what looks like a registry hack on some specific devices)

How to get a cover to stop screen interactions while in my pocket, nor do I want to hear about a more elaborate lock screen to keep said interactions from interfering with alarms/calls. The problem is simply that the screen comes on at all with seemingly no way to change the behavior.
