Just converting from floating point to fixed point is likely to be
slower on "hot" boxes. Please consider this (old!) snippet from the
TODO file:

The advantage of this scheme is that you don't have to write back the
results, a single compare is sufficient except when the object is
updated.

This idea has been around forever - sometime it will be reality, and
the protocol should allow for it. :-)
PPS: Some of the items in the TODO list have actually been
implemented/fixed. Mark, you shouldn't be afraid to change the list to
your own liking.
