Matthew Flatt f32ef95602 racket/gui: fix some concurrency problems `text%' ... Changed `open-output-text-editor' to put its additions into an edit sequence to better work with threads. Fixed problems in editor-canvas refresh and resize events, where the editor's refresh synchronization wasn't used properly. Fixed race conditions in the the protocol that is used to separate refreshes and edit sequences.
