How does reuse avoid false sharing between cores? Since this is concurrent hashmap we are talking about.

I focused on B/op because it was the only apparent weakness I saw. My “reuse” note was about allocation behavior, not false sharing. We’re talking about different concerns.

Allocation behavior when one core deletes and another adds and they reuse the same memory allocation is what I thought you meant.

Is that what you meant? Because if it is then you now have potential for the problem I described.
