> when syncCommitPhase=false then there is a window of inconsistency in the case multipel tx access the same key at the same time.
> This can be avoided by sending the lock release command after the commit command, in the same thread which is async triggered by the TM.commit. 
> This should be a very important performance buster for default configurations.
