I think we might be using it in a slightly unusual way: collect data for a while, do one big query once in a while to aggregate/transform the data and clean everything. Rinse and repeat as it's a background app. So lots of allocations/deallocations. If you're only storing a few key/value pairs long term, you won't have any issues.
