Daniel Micay b883d6a54c simplify the exchange allocator
* stop using an atomic counter, this has a significant cost and
  valgrind will already catch these leaks
* remove the extra layer of function calls
* remove the assert of non-null in free, freeing null is well defined
  but throwing a failure from free will not be
* stop initializing the `prev`/`next` pointers
* abort on out-of-memory, failing won't necessarily work
