This is easily worked around by having a Geomety bump the 
Precision Model Object refcnt in its constructor and decrementing 
the refcnt in its destructor

Another perhaps *faster* method is to have the Precison Model 
refcnt bumped twice by the highest level invoking function 
 
This will ensure that the Precison Model refcnt will never fall to zero
hence not be deleted by any operations before the high level calling
routine is ready to return at which time it decrements the extra refcnt.
