> When the user calls {{AtomicHashMap.put(k, v)}}, {{AtomicHashMapProxy.getDeltaMapForWrite()}} first reads the atomic map in the invocation context, and only acquires a lock afterwards.
> Between the read and the lock, another transaction can write something to the atomic map, and that write will be lost.
