    kernel - close holes in autoconf's run_interrupt_driven_config_hooks()
    
    * Interlock with a ran_config_hooks static variable instead of 'cold'
    
    * Get rid of list races which might occur due to hooks being removed
      while the hooks are being run.
    
    * Use a finer 1-second sleep interval instead of a 10-second sleep.
