rstat doesn't currently have a flush throttling mechanism cuz it doens't expect readers to be super hot but adding one should be pretty easy - e.g. it can just keep track of the number of updates on this cpu since the last flush and then flush iff the it's above a certain threshold. Shouldn't be too difficult to match or exceed the performance and error characteristics of the existing code. Thanks. -- tejun
