Unfortunately, the big limitation of this is that we're going
through the FFI to get things to work.

This kinda sucks because that means that the exported functions
have to stick to exporting one of the prim_types (Int, Char,
Float, Double, Ptr, StablePtr, and a few others).

So, is there some wizardry out there which allows using the RTS
Linker to load up .o modules which are not created with the FFI?
I've been experimenting with it, and I just get segfaults if
I try to load the adder_closure, adder_entry, adder_fast1 or
adder_info symbols.
