Some background. At least in our implementation, removing each individual item is significantly slower than removing and recreating the objectStore. It's also significantly slower than a 'clear' function is. And while tearing down and recreating the objectStore works, it's fairly complex if there are multiple indexes on the store. Adding a clear() function, while redundant, should make things easier for developers while adding very little work in the implementation. I think there is a bug in the above proposal though. clear() should return a IDBRequest. However the .result of the request should likely be null. / Jonas
