> The test may fail the following assertion if async edit logs are enabled:
> {{logging edit without syncing should do not affect txid expected:<1> but
> was:<2>}}. The async thread is doing batched syncs in the background.
> logSync just ensures the edit is durable, so the txid may increase prior to
> sync. It's a race.
