Yonik Seeley updated LUCENE-2751:
---------------------------------

    Attachment: LUCENE-2751.patch

Whew, this code is complex, and I don't really have a solution I like.

Here's a patch to IntValuesCreator that's only for brainstorming purposes...
- synchronize on the entry instead of the creator so more than one segment may be loaded concurrently.
 This is needed to publish objects safely.
- when guessing the parser, don't set it until it succeeds - basically split up setParserAndResetCounts()
to set the counts first, but the parser last.
- when setting/checking the parser, we need to synchronize on the creator

I also just realized that the mere act of checking the cache creates objects (see the base
getCacheKey() ).

> Most tests in the search package don't care about what kind of searcher they use.
> we should randomly use MultiSearcher or ParallelMultiSearcher sometimes in tests.
