Interestingly enough I noticed it didn't happen when I dragged in a URL from my browser (via the site icon) instead of copying and pasting the URL of the text. This produced a different font than my customized font for notes ("Chalkduster"). I then tried switching my default font for notes to a more standard Arial, and things went back to normal. I can now copy and paste hyperlinks to assets in other apps (like Mail, Curio, etc.) and it doesn't hog the CPU. That is odd behavior - it doesn't seem to like a certain type of font in the notes field.
