Currently, generates a vector of all data keys that can potentially be deleted, then collapses that vector to a hash set.
In the case where a symbol is being appended to constantly, this results in a large amount of duplication in the vector.
Materialising AtomKeys is also generally memory hungry, and not needed in this case.
