with-apollo ssr memory leak

[ITSWYoo]

If the with-apollo example is used, a memory leak of apollo objects occurs in node in ssr.
ex) ApolloLink, ApolloClient, ApolloCache, ApolloError
When useQuery is used, memory is released because useEffect calls queryData.cleanup().
but, in ssr, useEffect does not call.

In apollo-client test code, https://github.com/apollographql/apollo-client/blob/main/scripts/memory/tests.js#L236
after getDataFromTree, client.stop() is called.

How to solve with-apollo's example?
When to run apolloClient.stop()?

Has any developer experienced this issue?
