When tern is started with node.js starts, it waits 1 seconds (can be configurated in settings) and try to get the port of the started of node.js to know the URL of the server.

With big Tern plugin (like AUI, YUI), 1 sec is not enough. To fix that, we can configure settings to 2 sec, but I think we should add new settings (number of times that it must retry to get the port) to avoid waiting 2 sec each time.
