If the old precompiled object is still in the statedump, it's still
being used somewhere.  Presumably, it is inherited by something else.
You can get rid of it by recompiling those other objects as well, to
make them inherit the new, interpreted version.

The proper way to upgrade precompiled objects is:

1) recompile them to interpreted objects, which may be changed
2) recompile all the objects that inherit the old precompiled objects,
   as well
3) reboot with a driver in which the interpreted objects are replaced
   by precompiled objects, which must match the interpreted ones
