 Replying to [comment:19 Lars Aksel Opsahl]:
 > So if ST_Distance in postgis had used the same GEOS call that you do it
 would have worked ?

 In this specific case YES, I've tried it and if `ST_Distance` used
 GEOSDistance the test would pass. I guess the reason to use liblwgeom
 would be avoidinng the conversion to GEOS but if it gives wrong answers we
 could switch over.

 What Martin says about distance being not robust enough remains as a
 problem though...
