To reference WoW again... when you are initiated in combat, zombie following you or player attacked you, you can't log out until youre uninitiated.. Either you ran away from zombie or you die/kill opponent. also when you die your body stays live for x amount of time to be looted. I always give the courtesy to stay on the dead screen for 1 min after I am killed by a player to give him/her a chance to loot.
