Ok, so you still need a step where you reserve, which can fail and
only after that guarantee you can allocate up to the reservation?  I.e.
not a replacement for mempools?  Just asking because I recently had
to implement a mempool_alloc_batch to allow grabbing multiple objects
out of a mempool safely for something I'm working on.
