If running bluetoothctl as a subprocess from another process, and piping
input to it, it’s possible for the stdin pipe to be closed by the parent
process while there’s still data pending in its buffer. This results in
input handler callbacks with condition (G_IO_IN | G_IO_HUP). All of the
pending input should be handled before closing bluetoothctl.
