Research direction

Start with the original BPO issue 42154 and investigate BaseManager proxy behavior when its server restarts. Reproduce the immediate bad-proxy return, then identify the relevant multiprocessing library code and add coverage for the restart case; done means the proxy no longer returns immediately in that scenario.
