Michael McCandless updated LUCENE-3897:
---------------------------------------
Attachment: LUCENE-3897.patch
Christian and I discusses this on IRC... and it seems like the only real course

to prune all but the least cost partial path.
I implemented that approach (patch) and now this seed passes... I'll beast some
more.
