What about valgrind --tool=callgrind and then kcachegrind? No need for
any special profiling flags.

Make sure to set CGAL_DISABLE_ROUNDING_MATH_CHECK.

Sparsity pattern computation dead slow with 'real' spaces

Bug description:
The computation of the sparsity pattern is dead slow when real spaces are used, i.e.,

    R = FunctionSpace(mesh, 'R', 0)

To see the problem, compare the neumann-poisson and poisson demos with fine meshes (256x256)
