Geodjango transform introduces large errors

Geodjango's .transform() method works as expected on GEOS geometry objects. Small numerical rounding errors appear, as expected. However, attempting to save a GEOS point with a given SRID to a table with a different SRID leads to some kind of implicit transform call that introduces much more significant and problematic numerical errors.
