> With separate DocumentsWriterPerThreads (DWPT) it can currently happen that the delete
part of an updateDocument() is flushed and committed separately from the corresponding new
document.
> We need to make sure that updateDocument() is always an atomic operation from a IW.commit()
and IW.getReader() perspective.  See LUCENE-2324 for more details.
