What I meant was that the hz value changes rarely.  Whenever it
changes you must recompute the constant to multiply by (which
is somewhat expensive), but from then on you only need to multiply
when "dividing".  You do need a multiplication that is 32x32 -> 64
bit (assuming 32 bit int) for this to work.

Anyway, this was just a thought that occurred to me.
