Honestly, I don't fully understand why we have the customizable
allocation at all. I'm aware of only one real usecase, and that's hooks
into certain types of garbage collectors. And then there's some
*potential* to use them to implement better recovery on allocation
failure, as has been discussed recently, but no one is doing that for
real as far as I know.

To make it possible to really stay in full control of allocation with
GMP, another option is to push forward with the itch/scratch-ifying of
the mpn functions, and then stick to using mpn.
