Wasn't it the other way round for previous versions? Anyway, I think this is the way to go, but we can't do it on all architectures because some of them are still not NPTL-enabled. We also should get it right early because changing the mutex algorithm changes the database environment layout in a way which cannot detected by Berkeley DB. If you think it's not too late for that, we can make the change now, or with the release of version 4.8. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
