I was looking into the sparsity pattern code a bit, and I was wondering
if the !need_full_sparsity_pattern branch in
SparsityPattern::Build::parallel_sync() over-estimates n_nz and n_oz? It
doesn't do the equivalent of the my_row.erase operation that we have in
the need_full_sparsity_pattern branch, and hence it presumably can
double-count some dofs, no?
This isn't a big deal for me, but I was just curious if this is indeed
the case.
