I thought that Webkit's current behavior was to not paint the text but 
to still
lay it out with some sort of default metrics while painting other 
things on the
page...  If so, doesn't that still cause flicker when you switch to using the
right metrics, because non-text parts of the page, or text parts that are not
using the downloadable font, end up moving around when the font loads?

Or do you block all painting of the page while loading a downloadable font?
