> Distributed transactional cache:
> 1. A sends Prepare to B
> 2. B receives Prepare, but due to ongoing ST it is blocked
> 3. B replication timeout elapses
> 4. B sends Rollback, this does not find the TX as Prepare was not executed yet. The transaction is put into completedTransactions.
> 5. Completed transactions timeout elapses. This is by default 15 seconds, way shorter than ST timeout (due to which the Prepare was blocked)
> 6. Prepare is executed on B, acquiring lock on K
> Nobody will rollback the TX as originator thinks it was already rolled back.
> Result: key K will be locked forever, all attempts to update/remove it will fail.
