 242          * way to get a callback from when a stylesheet is loaded (that is, including any
 243          * @import rules inside). To work around this, we'll have a little time loop to check
 244          * if the styles apply.
 245          * Note: This test originally used new Image() and onerror to get a callback
 246          * when the url is loaded, but that is fragile since it doesn't monitor the
 247          * same request as the css @import, and Safari 4 has issues with
 248          * onerror/onload not being fired at all in weird cases like this.
