Nice!

We could probably add more suppressions to the dolfin_mpi.supp (and maybe 
rename that file because it not only contains suppressions for mpi), so the 
memory test also pass with mpi.

I have run the memory test on the la/unit/python/test.py and I know that there 
are some issues with the hand made python wrapper of the data() functions for 
matrices. (I fixed this, but forgot to commit it and now an hg update -C has 
removed it.) Will look at it again... 

I also spotted some memory leaks in the Epetra backend, especially in the 
SparsityPattern class.

Should we also run the unit tests through the memory tester?
