That won't work, because the input size is unlimited and memory is not.
You need to be able to fall back to disk.

That's insufficient too; just allowing out-of-order ranges means
that some kind of buffering will be needed.

The only safe strategy is to do what "sort" does, and copy the input
to a disk file.
