	But what is the purpose of a finalization function that doesn't have a 
side effect?  They are defined as (;a -> unit) which implies to me that 
the only purpose of the thing is to produce a side effect.

	close() seems to be conceptually the same finalization as free() to 
me.  It releases a system resource back to the process that would 
otherwise be unavailable forever.
