That's certainly an interesting approach.

It's got a maximum latency problem though.

If for some reason the unlucky thread that acquires the lock cannot process the batch faster than other threads are adding.... well that ends poorly

That would require a write rate very atypical for a cache and easily mitigated, though largely an almost impossible scenario.
