That's what I meant by the sentence _The dynamic table has a maximum size which is specified at the beginning of the connection and which never changes afterwards._

> You tentatively calculate `MaxEntries` based on the remembered value, and prohibit sending more than `MaxEntries` entries prior to seeing the SETTINGS frame. Once you see the SETTINGS frame, you know where the wrap point actually is and you can wrap if you need to. For any reasonable value of the bound, that prohibition shouldn't be an issue.

That's a good idea.  You can actually send up to `MaxEntries * CeilMul` (whatever `CeilMul` is set to in the end) until you see the _SETTINGS_ frame.
