> All external calls from a {{RpcEndpoint}} can be potentially blocking, e.g. calls to
the {{FatalErrorHandler}}. Therefore, I propose to make all these calls coming from the {{RpcEndpoint's}}
main thread non-blocking by running them in an {{Executor}}. That way the main thread will
never be blocked.
