Limits of concurrency control

[mikesperber]

LG 5-4 reads as though ACID databases typically provide serializable transactions, which they don't.

(See, for example: Warszawski, Bailis ACIDRain: Concurrency-Related Attacks on Database-Backed Web Applications.)

Therefore, the curriculum should contain wording to the effect that participants should be aware of transaction isolation levels, that serializable has serious performance drawbacks and is almost never the default, and that writing applications that assume serializable and running them with databases that don't implement it poses risks.
