Quick follow up question -- does reg.finalizer() use the "on exit"
option. (If not, perhaps it could be added as a flag?)

It doesn't, but it might be added. Patches will be considered. (But how
did you manage to use .Call on

void R_RegisterFinalizerEx(SEXP s, SEXP fun, Rboolean onexit)

?? I thought all the arguments had to be SEXP in that interface.)

Horrible things will happen on a 64-bit machine, where Rboolean and SEXP
are different lengths, but on a 32bit machine the argument passing is
likely to work (for suitably restricted definitions of `work').  I'm more
impressed by the fact you could .Call a void function when .Call expects a
SEXP return.
