This is probably my fault. I recently added some functionality to the 
UMFPACK (uBLAS) interface that makes it possible to split the 
factorization from the solve step. This is very nice if the matrix is 
assembled once and used many times, as in the conv-diff demo. However, I 
have not done the same in the PETSc-LU class (since I've never used 
PETSc). Please revert the demo. Sorry. /Dag
