Well done!
I've disabled the TimedBuffer for the `MAPPED` journal when `data-sync` is
`false`, here: https://github.com/apache/activemq-artemis/pull/1436
But I've not found any change on the code here to avoid the use of a
TimedBuffer: it needs to be added yet?
P.S.: In that case I can close my PR, that is addressed by this one :+1: ---
