Comment (by pramsey):

 I think this is a "won't fix". I've added some extra interrupt points to
 GEOS 3.9+ that were missing relative to the older versions, but I can't
 see a way to do anything without potentially impacting normal operations
 for smaller geometries. You've just got an extra nasty case here that
 happens to have some very long run-times for some of the stages of the
 union.
