DBQ: is silent failure a good idea? Perhaps a printout or something?

Just curious...

It isn't a great idea. However, server runs headless (that is, the client starts
the process) and uses stdin and stdout to communicate with the client. If we
write to stdout it will break some clients. If we write to stderr it will
probably be ignored by clients. We could send a non-fatal "server failure"
notification, but as far as I know existing clients would just ignore it.

So, I'm not sure how to get any output to anyone that needs to know. Suggestions
welcome.
