reading from InMemoryCache causes memory leak (in React Native)

See original GitHub issue

Intended outcome:

Calling readFragment/writeFragment should not increase memory usage at all.

Actual outcome:

Callling readFreagment and then writeFragment repeatedly will increase the memory usage. Calling only readFragment without writeFragment will only increase the memory once, which I guess is some caching to avoid unnecessary reads?

How to reproduce the issue:

I have created a simple app with reproduction: apollo-memory-leak

Don’t know if it’s the same issue, but I’ve also noticed a possible memory leak regression related to cache after upgrading from 3.4.10 to 3.4.16

Unfortunately I can’t attach the full allocation sampling file as it contains proprietary code but here are some screenshots which might help:
