MCServer private dev survival server?

[xoft]

Actually the correct solution would be NOT to link worlds that don't exists in the first place. When the world is initialized and a link to a non-existing world is detected, the server should log a big fat warning with instructions on how to fix that, and disable the linking.
The server should never ever create a world that the admin didn't specify in settings.ini.

@NiLSPACE: The deadlock detector works by checking regularly if the world's time has changed; if the time doesn't change for the specified time, it considers this a deadlock. It cannot distinguish true deadlocks from work overload which is what this is.
