Describe the bug

When importing a .nar file created with nix-store --export using nix-store --import, then nix-store --import may fail saying error: out of memory. This is easy to reproduce using pkgs.quartus-prime-lite in nixpkgs whose exported contents are about 17G.

Steps To Reproduce

Export a large store path using nix-store --export > blah.nar
Import it again with cat blah.nar | nix-store --import (after deleting it or on another machine)
Observe an out of memory error.

Expected behavior

I expect the import to complete.

nix-env --version output

nix-env (Nix) 2.18.1

Additional context

This used to print a warning, but I had believed the warning was removed when all cases of this out of memory error were fixed. I'm not sure if this case was never fixed or there has been a regression.
