I'm not able to see problems for instance in the convection-diffusion demo,
after 38 steps.
So i'll guess that reducing it to a small problem to find the bug will not be
easy.
I will try to clean and comment a little more my code, and if i find that i'm
not doing something really stupid, and if the bug persists i'll send my code.
It's a 3D stokes problem with taylor-hood elements solved by an uzawa
algorithm.
