Comment:
GHC has support for registering Haskell functions as finalizers, see the
module Foreign.Concurrent. The problem is that it isn't practical to
guarantee that finalizers all run before program exit when the finalizers
themselves are Haskell code (The Boehm paper on finalizers has the
rationale: [http://citeseer.ist.psu.edu/boehm03destructors.html]).
However, we could make an exception for C finalizers registered via
`Foreign.ForeignPtr`, and give these extra guarantees. This has been
requested before, and I think it would be a useful feature.
