Nice!  And you can delete a little more:  Move the "_slow" versions into DEBUG_ONLY builds, or even kill them off.

Archaeological Note: The Klass virtuals were the original functions (sans "_slow"), but now exist only in order to provide a cross-check on the validity of the LH-based tests.  The LH-based tests appear to be working correctly now.  :-)
