Shai Erera updated LUCENE-2721:
-------------------------------

    Attachment: LUCENE-2721.patch

Simon, looks like we were working on it in parallel :).

The patch you added only takes care of that particular test case. This patch ensures all test
cases won't be hit by this randomness problem, by ensuring IWC is not configured to flush
by num docs or small RAM buffer size.

Patch is against 3x, I'll port to trunk after I commit.
