There were some changes to the core recently to address synchronization/concurrency issue. Maybe they have had an effect?

Neo4j-spatial importing OSM data (which uses lucene to find matching nodes for ways) is suddenly running much slower than usual on non-batch imports. For most of my medium sized test cases, I normally have surprisingly similar import times for batch inserter and non-batch inserter (EmbeddedGraphDatabase) versions of the OSM import, but in recent runs the normal API is now more than 10 times slower. Down to 70 nodes per second, which is insanely slow. Any idea if there is something in the recent snapshots for me to look into? Reproducing the problem requires simply running the TestOSMImport test cases in neo4j-spatial. I have only tried this on my laptop, so I have not ruled out that there is something local going on.
