About the same. CartesianCoordinates is only included b/c some other
thorn in there needed a thorn that implements "Coordinates". Now that
Llama is in the ET one can just use its own "Coordinates" thorn with
the proper single-box settings.

CoreCollapseControl could likely be replaced by thorn Trigger (and a
large number of triggers).

Yes the failure is a con2prim failure though the density is not yet
that high (3.420260e-03 up from initially 3.15e-3 which in itself is
actually quite high, hmm, maybe that is where the problem comes from.)
