S ) �CockpitProblema� A type of exception that carries a problem code and a message.
Depending on the scope, this is used to handle shutting down:
- an individual channel (sends problem code in the close message)
- peer connections (sends problem code in close message for each open channel)
- the main stdio interaction with the bridge
It is usually thrown in response to some violation of expected protocol
when parsing messages, connecting to a peer, or opening a channel.
