Updating iTunes while Traktor is running

You can update iTunes while Traktor is running (drag songs into playlists etc) no problem.

In Traktor you can right click the 'iTunes' library and select Refresh and any changes you've made will be brought into the Traktor iTunes playlists.  Doing this with Traktor playing works fine and doesn't appear to affect anything (played state of tracks isn't changed for instance).
