That shouldn't be too much trouble. We have a lot of things in the
library that are already prepared for the "he just deleted an element
but hasn't renumbered yet" case; the parallel communication stuff
probably just slipped under the radar since it was only getting called
for ParallelMesh or right after generation of a contiguous numbering.
By the way, ParallelMesh currently has an "insert_node()" interface (Oct. 2007)
but it seems a little unsafe? If n->id() ==
invalid_id it will still add the Node... I only bring it up since I was going
to add a MeshBase::insert_node() interface and
came across this in the process.
Hmm... that looks like an anachronism from the original ParallelMesh
design. It's never even used inside library code any more. I suppose
you could assert(valid_id()) but I'd be okay with just outright
deleting the method.
