-----------------------------------------

Hey Jason,

My tests are inconclusive on the patch posted above.  LUCENE-2215, however, seems promising
and good to get into Solr as well.

it would be nice to offer some other Collectors that are better at handling really large number
of results.  This could be implemented in a variety of ways via Collectors.  For instance,
we could have a raw collector that does no sorting and just returns the ScoreDocs, or we could
do as Mike suggests and have Collectors that have heuristics about memory tradeoffs and only
heapify when appropriate.
