A value != 0 means that the shouldn't remove any units from the map, usually because we are currently operating on a unit& and removing it might cause memory corruptions note that we don't check for the dtor of lua owned units because we assume that we operate on such a unit that the lua function that invoked the operation on that unit (like wesnoth.units.add_modification, wesnoth.units.matches ..) have a local copy of that lua_unit* userdata in its stack that prevents it from being collected.
