I consider that broken behavior, which is why the standard was clarified
in 2.3 to allow non_existent() to throw exceptions.
non_existent() returning true when it can't contact the server is likely
returning a lie.
Just write your own wrapper function that calls non_existent(), catches
the exceptions you want, and returns different error codes for different
exceptions. Once you've done that, you can reuse that code everywhere
without having to write lots of catch() blocks.
