Every guest thread is a host thread, and the game makes and ends them all through play. A thread that slept through plat_wait_ns kept a waitable timer, one that read or wrote a file an event for each, and one that decoded zstd through the host a decoder context of about 100 KiB; nothing closed or freed them when the thread ended, and a detached thread's own record stayed allocated. They are now given back when the thread's function returns: the handles in win32.c thread_main, the decoder context through plat_thread_end_hook, and the record by whichever of the thread and its detach comes last. tests/thread_end_check.py runs 416 such threads and compares the process's handle count before and after. tests/sync_wake_check.c gets the two stand-ins kernel.c has needed since the service wait log, so that check builds and passes again. The Linux file only gains the hook call and was not compiled here. Co-Authored-By: Claude Fable 5.2 <noreply@anthropic.com>

"""Build and run tests/thread_end_check.c: what a thread keeps for itself is given back when it ends
