"""Automatic verification that the ANUGA fitting code is not taking more time
or memory than usual.  This test has been tailored for computers in GA.

I'm leaving a 20% error margin

Note, going from version 4897 to 4917 uses more memory, based on how
memory is measured here. What is actually happening is the mesh
generation is using less memory, in version 4917.  In version 4897
mesh gen uses and frees up more memory, so python asks for less extra
memory in the fitting stage.  So overall version 4917 is an
improvement.
