Disabling the i2c sensors (color, navx, range) when they are not being used will improve the update times significantly.

Look for code samples from Philbot and mikets.

In the end, we abandoned this disabling/reenabling sequence as the currently suggested method seems to cause more problems than it solves. The color sensor gets stale values after re-enabling, and this affects the reliability in non-deterministic way.

The original problem with i2c bus overload seems to have mostly diminished after we started using 2 CDIMs instead of just 1.
