I think this will need changes before it can be integrated as there are naming issues and needs the timeout to at least be able to distinguish immediately selection operations from others. There are quite a few use-cases to work through on how it might be used too.

Isn't this a replacement for the existing instrumentation? If these are new events I am sorry.

What is keeping us from removing ASM in that case?
