> This came up on a dist-list conversation between Andy P., Ted Yu, and myself.  Andy noted that extremely large lists passed into put(List) can cause issues.  Ted suggested that having doPut check the write-buffer length every so often (5-10 records?) so the flush doesn't happen only at the end, and I think that's good idea.
>  public void put(final List<Put> puts) throws IOException {
>     doPut(puts);
>   }
>   private void doPut(final List<Put> puts) throws IOException {
>     for (Put put : puts) {
>       validatePut(put);
>       writeBuffer.add(put);
>       currentWriteBufferSize += put.heapSize();
>     }
>     if (autoFlush || currentWriteBufferSize > writeBufferSize) {
>       flushCommits();
>     }
>   }
> Once this change is made, remove the comment in HBASE-4142 about large lists being a performance problem.
