No, I don't think so.

  code:

  -------------------------------------------------
  --         Put your Lua functions here.        --
  --                                             --
  -- Note that you can also use external Scripts --
  -------------------------------------------------
  function makeMap()
  id = 0
  for i=0,100 do
  	for j=0, 100 do
  		addRoom(id)
  		--setRoomArea(id,0) --uncomment this and remove below call to avoid seg faults
  		setRoomName(id, tostring(id))
  		setRoomCoordinates(id, i, j, 0)
  		setExit(id-1,id,1)
  		setExit(id,id-1,2)
  		setRoomArea(id,0)
  		id = id+1	
  	end
  end
  end

  function makeLabels()
  	id=1
  	for i=0,100 do
  		for j=0, 100 do
  			--display(id)
  			x,y,z = getRoomCoordinates(id)
  			createMapLabel(0,tostring(id),x,y,z,0,255,0,0,0,0) 
  			id = id+1
  		end
  	end
  end

  --makeMap()
  --makeLabels()
  centerview(1)

  uncomment makeMap and it crashes. It fails when id is 1 as well, so it
  isn't because of the i-1 setExit bit. It's caused by mpRoomDB not
  being initialized because there is no area created. Even post
  creation, the room needs to be assigned to an area first before any
  calls to mpRoomDB are called, else it will seg fault. It seems like we
  need some 'void' area that has no name and is just an abyss for rooms
  waiting to be allocated to avoid breaking scripts.
