(In reply to comment #40)

One more thing: my previous benchmarks were wrong, I had an error in my setup. 
With a correct benchmark, polyhedron improves slightly in the testcases where
the change is outside the measurement noise.  This includes capacita.f90 which
gains some 2%.  Further, and as expected, with the patch, Thomas's testcases
from comment #6 both run at the same speed that only the 'call by value'
version did without the patch.
