- hinkley 1y agoCPU cache means that the same value read twice will return the same value. Some exceptions for NUMA, and mu[tiple threads. But two reads of a cache cache make no such guarantees. There is a vast number of undiagnosed race conditions in modern code cause by cache eviction in the middle of 'transactions' under high system load.
