This is actually something Cake's shaper can already cope with.  I did some testing on an ancient PC that didn't have HPET hardware, so timer interrupts only had 1ms resolution even on Linux.  This merely results in small bursts of traffic at 1ms intervals, which collectively add up to the configured rate.
