If this is a one-time batch insertion then should really use the batch
inserter <http://wiki.neo4j.org/content/Batch_Insert> which is optimized for
these things. It's much faster for imports of this sort and you don't have
to (in fact, you cannot have) multiple threads inserting you
them. That would mean that those locks are held
until that thread has committed its transaction, this will make it look like
it's only one thread at a time committing stuff.

Scratch that... you can do:

new SortField( "name", SortFie
Btw I don't think lucene can do that kind of multiple-field sorting for you,
