   @areusch We only do it for CopyFromRemote and CopyToRemote. In both cases, we(user or rpc server) allocate temp meomory from the arena, which will become invalid after the response period. The user do not guarantee these byte arrays stays alive after the call ends. So that is why explicit sync is needed here.
   
   For DeviceAPI::CopyDataFromTo, we do not run the sync, since the resources are NDArrays managed by the remote user, and the remote user can choose to call sync after the copy
