Review comment:
We are not using file regions on xnio with this pr, but chunked nio files,
that are correctly handled by Netty and xnio receive just ByteBufs. The wildfly
tests (and the one from @wy96f ) shows that replication is happening until a
certain point, but seems that something is getting blocked on the Netty thread
and we will time out on `replicator.sendSynchronizationDone(nodeID,
initialReplicationSyncTimeout, ioCriticalErrorListener)` because of the pending
writes of chunks.
