Additionally, unless something's changed recently in ASDF, calls to
OPERATE in .asd files (e.g., ensure the availability of ASDF extensions)
will cause output to be printed, so while you're handling warnings, you
might as well redirect output too, e.g.,
(let ((*standard-output* (make-broadcast-stream)))
This will also effectively stifle output from systems that have
top-level forms that emit output, which do exist in the wild.
