The purpose in general is to get a globally unique, partition agnostic element
number. There may be a workaround for partition_unpartitioned_elements that
bypasses it. I'll see what I can do, but I'm a little compromised today...

No need to do that. Just don't call paral
The threading of the sparsity pattern is a bigger deal with amr when it is done
a lot, but in any case we could add a --single-threaded-sparsity or something
as an immediate stopgap.
And the hilbert indexing is used to derive a globally unique, partition
agnostic node number. But as you say it
The symptom with the sparsity pattern was that it would hangup forever in
DofMap::dof_indices(). ie all threads would be sitting at either
operator_new or delete for a std::vector inside DofMap::dof_indices().
Then, after taking forever on that if it ever got past it, a few threads
were still hun
Excellent. What was the symptom in te sparsity pattern?
I'll be flying most of the day, hopefully that'll provide me some time to stare

Win. Between fixing the localize() issue I brought up earlier and
de-threading SparsityPattern::Build() my job now ran! Hopefully the others
will continue to run as well.

Continuing my "huge run" witch hunt... I have really big runs that are
hanging at mutexes during threaded execution of SparsityPattern::Build().
The main issue seems to stem from DofMap::dof_indices(). Everything is
getting hung around allocating / deallocating std::vector objects
