Review comment:
The way we suggest changing memory pools in the docs is [set an
environment variable that changes the
default](https://arrow.apache.org/docs/cpp/memory.html#overriding-the-default-memory-pool).
So we'll capture that well here.
You *can* pass a different pool to individual functions. We'll miss those
allocations here, but since we show which allocator we are tracking, I think
that's fine. It's at least clear about which allocator it's showing.
