    buffer-forall now disables async
    
    Before, the command
    
      buffer-forall buffer-export
    
    only exported one buffer for me. With async disabled, the command
    works as documented and successfully exports all buffers.
    
    Also before, I received an assertion from
    
      buffer-forall buffer-close
    
    which caused a SIGSEGV at #9422. Now, the action works as expected.
