I think a lot of benefit can be had by making ForeignPtr a product type rather than a union one. being able to unbox it in constructors and opening it to CPR analysis is key for tight inner loop code which pointers will most definitly be involved in.

Actually this is what we did, and why the benchmarks go a lot faster with GHC 6.5 compared to 6.4.x. Cheers, Simon
