What is exactly Is it just handling the lockscreen? If I set my device not to lock when screen is turned off, can I safely freeze/remove

I'm using a galaxy nexus with cyanogenmod 11 (kitkat), trying to lower RAM usage.

up vote 3 down vote accepted runs your lockscreen, home button, and a few other things I can't remember.

It's an integral part of Android. Don't remove it.

If you disable/freeze, your device's Home button will stop working until you enable/unfreeze it. This process keeps running all the time, but it is not a Battery drainer so don't worry and don't disable it.
