What happens if you have distributed mnesia, and a 'sequences' table
where two nodes run dirty_update_counter at the same time?

My guess is that both could get the same number?

Thinking out loud:
If so, I guess one could use {local_content, true} on each node's
"sequence" table and make the key one have be {node(), SequenceId}.
