IMPORTANT: This cache intentionally does NOT close clients on eviction.

Evicted clients may still be in use by in-flight requests. Closing them

eagerly causes ``RuntimeError: Cannot send a request, as the client has

been closed.`` errors in production after the TTL (1 hour) expires.

Clients that are no longer referenced will be garbage-collected normally.
