We have a problem at the moment when using PETSc related to conflicts 
between dolfin::MPIManager and dolfin::PETScManger as to who should 
initialise and finalise MPI. The difficulty is that we can't control the 
order in which MPIManager and PETScManager are destroyed.

Given that we will probably have more 'manager' classes in the future 
(e.g. for Trilinos), what is the best approach? Some possibilities are 
one 'Manager' class that does the lot, or a SingletonManager which can 
control the order in which singleton manager classes are destroyed. Ideas?
