this seems low? Also I think we want mutliple processes, instead of just multiple workers.

Done in commit ea61173:
- Raised the load:
NUM_WORKERS6 -> 16,OPS_PER_WORKER12 -> 50. - Added
test_multiprocess_concurrent_clients_stay_consistent, which spawnsNUM_PROCESSES=4separate processes (viamultiprocessing.get_context("fork")), each building its OWN accelerated client +Tableand driving it fromWORKERS_PER_PROCESS=8concurrent threads. Since the daemon is spawned per-Table(verified inclient.py/_daemon.py), each process gets its own daemon + UDS, so this genuinely exercises inter-process concurrency (multiple independent daemons) on top of the existing intra-process thread-safety test. Every worker owns a disjoint worker-id block / key prefix, and each child reports(ok, touched_keys, error)back over a queue so any cross-process interference or exception fails the test; the parent tracks touched keys with the janitor for cleanup. Regenerated the CrossSync sync twin.

Adds accelerator concurrency and thread-safety tests (async + autogen).
Part of the accelerator test stack. Stacked on top of #11.
