In fact I already tried with a crude patch, just to get an idea. The main problem with using http://java.sun.com/j2se/1.5.0/docs/api/java/util/concurrent/locks/ReentrantReadWriteLock.html is that you cannot upgrade read locks and have them become write locks. That class is designed so that you have to relinquish all your read locks before attempting to grab a write lock, or you're deadlock on yourself. Unfortunately the existing code likes to grab read locks and then grab write ones too, killing itself. Being a non trivial change, I'll put it on hold and see if I can get some speedup elsewhere, but I was wondering, is that (grabbing the write lock while still possessing a read lock) supposed to be happening, or is it just a bug in how the lock calls are being made?
