---------------------------------------------------------------------
I took a quick look at the patch. Instead of tracking {{lastFlushIndex}}, it
may be easier to track an {{AtomicReference}} to the entry in the buffer-list.
{{totalSuccessfulFlushedData}} might run into GBs (for larger block sizes) and
overflow an integer. Let's use {{long}} for this.
