      One idea would be to defer the construction of the TransactionCoordinator object until the coordinateCommitTransaction command is received. This way for a single-transaction or other transaction commit types which don't require two-phase commit the system wouldn't need to run TransactionCoordinator::_done() as a task on the fixed executor to simply destroy the TransactionCoordinator object and decrement counters.
