I'm not opposed to this.

There is a question of how much we want to be tolerant of sloppy users
versus being strict within the library. I think the tactic above (and/or
simply leave it uninitialized and count on valgrind to let us know) would
be good to use in PETSc tests. I'm not sure it's worth pushing on users as
the default.
