I'm currently looking at the parallel-correctness problems Ataollah
Mesgarnejad and Vikram Garg are having, and it appears that the simple
workaround for both of them involves sticking the right
ghosted_vector.localize(ghosted_vector) call in the right place...

Except, I can't find the right NumericVector::localize() call!  All
our localize-from-NumVec-to-NumVec calls seem to be designed around
the assumption that the source and target vectors are different, and
therefore we need to spend a bunch of time copying local coefficients
around rather than just ghosted coefficients.  Am I misinterpreting
our localize() methods, or do we need to add something new for
ghosted vector localization-to-self communications?
