 ThreadPool: closure with class-name return type (regression: arg_info[-1].type not deep-copied)
---XFAIL--
-Returning a Closure from a worker thread is not yet implemented.
-The worker creates a per-result closure snapshot in closure_transfer_obj
-(TRANSFER branch), but the result-closure's persistent shell ends up
-referencing memory in the task snapshot arena, which the worker frees
-in thread_pool_worker_handler before the main thread loads the result.
-This causes a heap-use-after-free in async_thread_create_closure when
-iterating bound_vars on the loading side. Proper support requires the
-result-closure snapshot to own its own arena and outlive the task
-snapshot until the loading thread consumes it.
