I don't know whether this is a toy example, having grid of this size is not
uncommon. True, it would make more sense to do distribute more work on each
box, if there was any. One has to find a proper balance, as with many other
things in life. I simply responded to a question by the OP.

I have the following code running in python 3.7:
def create_box(x_y):
return geometry.box(x_y[0] - 1, x_y[1], x_y[0], x_y[1] - 1)
x_range = range(1, 1001)
