-------------------------------------------------------------
[~ashleysommer] - thanks for the report. It looks like an execution time
variation of the problem of the original report for the ticket.
Here, the {{MultiUnion}} is not fully pushing down the transaction to the
component graphs. Normally (all from one database), this does not matter
because a transaction on one graph implies a transaction on all graphs. But
there are several separate TDB2 databases.
For background understand of the use case, why are there multiple TDB2
databases?
