Fix freeze due to door infinite loop
A certain arrangement of door-gears with a couple of pieces of sand next to it can get in a situation that causes an infinite loop, e.g. as if the sand nodes are trying to switch places with one another and form a circular dependency. The simplest patch for it is just to limit recursion for now. Randomness in the depth reduces the risk that machines themselves can get stuck in some pathological state.
