I would like to use DMGetLocalVector and DMGetGlobalVector with petsc4py 
but I didn't find the appropriate methods. If they are not implemented, 
I can do a PR with these functions and their Restore part.

I have an other problem: I have to optimize a Python function that take 
a numpy array given by the function getVecArray of a DMDA and I would 
like to use Pythran to do that. The problem is that Pythran doesn't 
recognize the array as a numpy array because the flags C_CONTIGUOUS and 
F_CONTIGUOUS are both set to False. Is there a reason that the 
C_CONTIGUOUS flag is set to False and not to True ?
