Indeed, it looks like StablePtr will get me what I want.  It's a
little less convenient than FunPtr because I'm already doing some
finalization of FunPtrs and I can reuse the same callback, but it
looks like it's specifically documented to do what I want, which is

In any case, memcpy still wins out on simplicity.  If I ever need to
pass a pointer larger than 32mb and have both haskell and C manage the
memory, I'll look into StablePtr.
