This is exactly the guarantee you _don't_ have. The only guarantee you have is that it _won't_ be run if the Ptr _is_ being referenced.
From the GHC library documentation:
newForeignPtr :: FinalizerPtr a -> Ptr a -> IO (ForeignPtr a) [...] The only guarantee is that the finaliser runs before the program terminates.
So it seems, finalization *is* guaranteed, just not promptness of finalization.
This is not true - finalization is not guaranteed.
If you use a StablePtr it will not be garbage collected.
You really should not poll anything - it is wasteful of system resources.
