Add a function to compute millisecond time difference quickly.
Our main function, though accurate on all platforms, can be very
slow on 32-bit hosts. This one is faster on all 32-bit hosts, and
accurate everywhere except apple, where it will typically be off by
1%. But since 32-bit apple is a relic anyway, I think we should be
fine.
