-A Foreign Object is just a boxed, unlifted, Addr#. They're needed
-because finalisers (weak pointers) can't watch Addr#s, they can only
-watch heap-resident objects.
-
-We can't use a lifted Addr# (such as Addr) because race conditions
-could bite us. For example, if the program deconstructed the Addr
-before passing its contents to a ccall, and a weak pointer was
-watching the Addr, the weak pointer might deduce that the Addr was
-dead before it really was.
