WAFFLE: Exposing Memory Ordering Bugs Efficiently with Active Delay Injection @Eurosys23

1. WAFFLE is about cheap ways to detect expensive bugs thus it's concerned with the design tradeoffs around concurrency bug detection tools (active delay injection in particular) compared to TSVD
2. In breaking down the design space for active delay injection, distills the essence of delay injection for the reader, which is useful
3. I'm interested in systems that exploit the physical time to avoid more expensive analysis when tackling hard concurrency problems (e.g., google's Spanner)

1. The oracle of injecting time does not find ABA data structure bugs. need to record a timestamp for not necessarily the happen before logic but other oracles to hunt that.
