Review Comment:
> Time t1: CREATE INDEX - Index descriptor with available = false is added
to the catalog. + schedules IndexBuild task.
...
> Time t2: Some time later IndexBuild task completes and sets available =
true for the index
...
Client starts a transaction at T2 + `ellison`: If `ellison ` is every small
than RW transaction obverses that the index is available, but RO transaction
won't because of an additional delay, see TxManager::currentTimestamp.
