  Log:
    thread_sync.c: remove unnecessary casts for queue_sleep
    
    "Qfalse" and "(VALUE)0" are equivalent, and do not matter
    for an ignored argument, either.
    
    Additionally, there's no reason to cast the pointer to
    rb_thread_sleep_deadly when we already have a queue_sleep
    wrapper.
    
    * thread_sync.c (queue_do_pop): avoid cast with Qfalse
      (rb_szqueue_push): ditto, use queue_sleep wrapper
