Even forgetting the threading issues (you need to make sure this happy
loop doesn't block the actual work StumpWM is designed to do..), where
are the stdandard-input and standard-output for StumpWM?

It is possible to define a wrapper to evaluate forms with 
standard-output collected and shown as a message; this is basically 
about using (with-output-to-string (s) (let ((*standard-output* s)) ..))
trick. But standard input is a more compliated thing.
