Strictly speaking, not quite.  We'll block until all external 
stylesheets in the currently-selected style set have finished loading. 
Alternate stylesheets do not block script execution.  So as of today, 
one can simple use alternate stylesheets for sheets that one does not 
need until end of pageload (though I fail to think of any cases where 
this would be desirable), then change the title/rel when desired.  At 
least in Gecko, this will do what Garrett wants.
