 =================================================
-Use the HACD convex hull routine in Bullet rather than the C# version.  
-        Speed up hullifying large meshes.
+Script changing rotation of child prim while vehicle moving (eg turning wheel) causes
+        the wheel to appear to jump back. Looks like sending position from previous update.
+Vehicle ride, get up, ride again. Second time vehicle does not act correctly.
+        Have to rez new vehicle and delete the old to fix situation.
+Hitting RESET on Nebadon's vehicle while riding causes vehicle to get into odd
+        position state where it will not settle onto ground properly, etc
+Two of Nebadon vehicles in a sim max the CPU. This is new.
 Enable vehicle border crossings (at least as poorly as ODE)
         Terrain skirts
         Avatar created in previous region and not new region when crossing border
         Vehicle recreated in new sim at small Z value (offset from root value?) (DONE)
-Lock axis
 Deleting a linkset while standing on the root will leave the physical shape of the root behind.
         Not sure if it is because standing on it. Done with large prim linksets.
 Linkset child rotations.
         Nebadon spiral tube has middle sections which are rotated wrong.
         Select linked spiral tube. Delink and note where the middle section ends up.
+Refarb compound linkset creation to create a pseudo-root for center-of-mass

 One sided meshes? Should terrain be built into a closed shape?
         When meshes get partially wedged into the terrain, they cannot push themselves out.
         It is possible that Bullet processes collisions whether entering or leaving a mesh.
