For some reason this didn't make it to the list yesterday BUT..

The slow line in your routine is the one that forces the layout manager
to recalculate the layout. You should only do this for notes whose text
has changed. That means you will either have to have a layout manager
and text storage for each note, or find a way of caching the glyph info
for each note so the shared layout manager can use it.

If you do this it will be waaaaay faster.
