-    Disable threading to fix non-determinism
-
-    A bug in the file parser can cause dependencies to be calculated
-    differently based on which files have already been parsed. This is more
-    likely to occur on systems with more CPUs.
-
-    Just disable threading for now. There is no noticable slowdown.
-
-    See #9891.

 Background images and other features can be added to DMG files by inserting a
