... just brainstorming a little...

How about a new object:
window.loadedScripts {DontEnum, DontDelete , ReadOnly}

All scripts are inserted as properties (using their URL as property
name) in it they have executed. So, one can do:

if ( 'http://example.net/niftylibrary.js' in window.loadedScripts)

More useful:
window.loadedScripts.addDependentFunction ( EventListener [, URL1 [,
URL2 [, ...]]] )

Executes the listener once all dependencies have been executed, or
immediately if already done.
