I tried saving the edited range of text in the text storage and then having my layout manager check this from:
-textStorage:edited:range:changeInLength:invalidatedRange:
Then my layout manager adds temp attribs in this method. Turns out that this is a Bad Thing (which I should have realised beforehand), as it can cause glyph generation before the text storage has ended editing. D'oh.

I haven't tried fixing temporary attributes in NSTextStorage - fixFontAttributeInRange:, but that might be worth a try.
