* this is a temporary check until chardevs can signal to |

168 |
* frontends that they are writable again. This prevents |
|
169 |
* the console from going into throttled mode (forever) |
|
170 |
* if virtio-console is connected to a pty without a |
|
171 |
* listener. Otherwise the guest spins forever. |

172 |
* We can revert this if |
|
173 |
* 1: chardevs can notify frondends |
|
174 |
* 2: the guest driver does not spin in these cases |
