Concurrent getTileImage() calls for the same tileIndex can occur unexpectedly when resizing a stream window. Adding a per-tile mutex is the simplest way to fix the problem and should not penalize performance too much as those events are rare. Returning an empty ImagePtr does not work (the stream blocks).
