Hooray, and very cool. I didn't know you only needed a locking mechanism if you only have multiple index writers so the use of NoLock by default makes perfect sense.
For Lucene, you do (did.. before lockless commits pach) need locking (a read lock) even to open an index with a reader. The write lock is still also needed to avoid a reader changing the index via deletion at the same time a writer is. Solr coordinates this at a higher level, hence it's not really needed. -Yonik
