Make @import actually create a rule and attempt some kind of fetch logic.
There's still a bunch of outstanding functionality here (like URL resolution and media list parsing).
Also, there's currently no way of telling the client to stop fetching data for a stylesheet (and, more importantly, not to attempt to access the stylesheet again as it's about to be destroyed)
