The emergence of fast, dense, nonvolatile main memory suggests that certain long-lived data might remain in their natural pointer-rich format across program runs and hardware reboots. Operations on such data must currently be instrumented with explicit write-back and fence instructions to ensure consistency in the wake of a crash. Techniques to minimize the cost of this instrumentation are an active topic of research.
