Don't request new tumbler thumbs if file only changed after the nth megabyte? (ie. downloads-in-progress)

Description

I noticed while downloading a film clip through Chromium, with the Downloads folder open in Thunar, that tumblerd was eating CPU. Since the thumbnail of the first 100 MB of the clip should be equal to the one of the first 200 MB, etc., would it be possible for Thunar to not request new thumbnails when a file has only been appended to?

I don't know how hard that is to keep track of … I'm assuming tumblerd doesn't/shouldn't be able to keep that kind of information along with the thumbnail, although it would of course be a more general solution if tumblerd itself could ignore these kinds of changes.
