Someone else emailed me an untested idea to just use exclude file and
place/remove/edit the exclude file to toggle the access.

That doesn't provide the truly graceful/informative response code or message,
but:
* toggles the access
* avoids downing the service even momentarily
* potentially avoids requiring a host admin to even do anything, since a user
may have permission to place/remove the exclude file
* it's at least distinct from failed to connect
* uses already existing features
* does not require any, let alone two different, wrapper layers in the form of
the perl (or other) wrapper script and (x)inetd to run it.

I haven't finished playing around with that to see just how close that can come
to the desired fully graceful process but I felt it should be mentioned as
another workaround option.
