A 400 doesn't indicate a problem with the worker or the system behind
the proxy, it indicates a problem with the client. Also marking a
worker bad for say a 401 unauthorized would make all authentication
impossible, a 403 or 404 would drain the pool every time someone asked
for something they weren't allowed to have or that wasn't located
where they thought it was (especially spiders like google).
