+Rom    26 Jan 2005
+    - The worker thread for a science application should be lowered for both
+      the graphics capable application and non-graphics capable.
+    - The graphics thread should now be set to a normal thread priority level
+      instead of high.
+
+    NOTE: The above changes were only implemented for Windows right now,
+          the pthread version of this stuff needs to be done.
