> This requires that when we swap FlowFiles Out that we always sync to ensure that we won't
have EOF if we've finished writing!!
> Also, in order to ensure that we don't increment the queue count on restart when the
file is incomplete, we need to write out to a temporary "xxxx.part" file and then rename to
xxxx after calling FileDescriptor.sync()
