Comment (by pramsey):

 I am going to move this to PostGIS GEOS and leave dormant, as Dan Baston
 has been working on some improvements in GEOS to handle curves natively
 that would kill several birds with one stone. It's a long term solution.
 In the meanwhile, the workarounds are

 - know this is an issue and use distance == 0 as your intersects test as
 necessary

 or

 - know this is an issue and preempt the built-in linearizer by pre-
 linearizing your inputs at the level you would prefer
