[Rd] Object finalization

[Timothy H. Keitt]

I see some code in R to attach finalizers to external pointer references 
(Register[C]Finalizer).  Anyone have an example of how to code the 
finalizer?  R_RegisterCFinalizer accepts a C function, but I can't see 
how to get it to operate on the pointer, since the pointer is not passed 
to the function when its called.  RegisterFinalizer takes an R closure, 
but how is it called from R (tried .Internal)?
