Even stronger: I wouldn't count on _anything_ more than that. On my
machine, time.time() changes value once per millisecond. I tested this
by looking at a loop that recorded time.time() 100000 times. The total
time in the loop was 61 ms; out of the 100000 numbers, 61 were higher
than the previous one, with the highest difference being 1.00017 ms,
the lowest 0.999928 ms.
