At least in Gecko, you can already detect whether the sheet is done 
loading: if you try to get its cssRules and that throws 
INVALID_ACCESS_ERR, then it's still loading.  (If it throws 
DOM_SECURITY_ERR then you're not allowed to read the style data; that's 
why you have to check for the exact type of exception thrown.  Though 
really, if you're loading style sheets cross-site you're in for a world 
of hurt unless you control both sites.)
