Follow the Linux shim's thread-count wait/wake pattern, close thread creation on the last detach, and synchronize the process exit status under the thread registry lock. This waits for guest completion only. Host-thread and broker-worker shutdown remain separate work: shim-only run_multithreaded_pe stress reproduced the ExitProcess allocator deadlock on repetition six.
Remove the platform's global SafeZoneAllocator declaration so Rust heap allocations use the default allocator. Leave guest page management and the MemoryProvider implementation unchanged. Avoid the slab spinlock involved in the observed ExitProcess TLS-cleanup deadlock. The rebuilt run_multithreaded_pe test and 50 sequential no-retry stress repetitions passed. Detached-worker shutdown remains a separate lifecycle concern.
