nlffi and memory management

Hello,

I have a question about nlffi. Is it possible to add an object 
allocated by to the smlnj heap, so that the garbage collector will 
remove it if no ml value points to it? I thought of using weak pointers 
for this, to call a finalizer which frees the real object wrapped in 
some ML value, but I would like to do it more "directly" without having 
to go through a list of weak pointers on each GC signal.
