 I generated a garden test using 2.0 garden and testing with 2.1 and sadly
 the thing kicked the bucket.

 This crashes the server service:

 I suspect this may be a GEOS bug because my parallel:

 {{{

 LIBJSON="UNKNOWN" RASTER
 }}}

 also crashes.  I'll try to swap out the GEOS to see if 2.0.3 still fails
 with older GEOS.
