Notes: Use <A HREF="../Sys/PetscOListAdd.html#PetscOListAdd">PetscOListAdd</A>(<A HREF="../Sys/PetscOList.html#PetscOList">PetscOList</A>,const char name[],<A HREF="../Sys/PETSC_NULL.html#PETSC_NULL">PETSC_NULL</A>) to truly remove the object from the list
<P>
Use this routine ONLY if you know that the object referenced will remain in existence until the pointing object is destroyed
<P>
Developer Note: this is to handle some cases that otherwise would result in having circular references so reference counts never got to zero
