                * thread.h: Include "list.h".
                (struct thread) [! NDEBUG]: Add field futex_waiter_node.
                [! NDEBUG]: Instantiate the futex_waiter list class.
                (futex_waiters) [! NDEBUG]: Declare.
                * server.c (futex_waiters) [! NDEBUG]: New variable.
                (server_loop) [! NDEBUG]: If we don't get an RPC for a while,
                dequeue all thread's enqueued on FUTEX_WAITERS and return 
EDEADLK.
                When blocking a thread on a futex, add THREAD to FUTEX_WAITERS.
                * object.c (object_wait_queue_dequeue) [! NDEBUG]: If
                THREAD->WAIT_REASON is THREAD_WAIT_FUTEX, unlink THREAD from
                FUTEX_WAITERS.
