An illustrative example how you are refusing to cooperate for
built-ins outside core but in the context of ISO.  This is open since
two years:

http://www.complang.tuwien.ac.at/ulrich/iso-prolog/length

9 systems were considered, 5 moved immediately after Lexington to the
agreed upon behaviour.  But not SWI.

Even more ironic in this case is that I have written the core list
traversal routines (first Floyd, then after I got the hint, Brent) for
SWI to make this fast.  It has nothing to do with your workload, it is
another issue.
