That would probably work, though perhaps we should
make this test a bit more general with something like the following?

Also Marcin, could you try out the latest snapshot (which will
also need the patch applied). It has another aarch64 specific patch included,
and it would be great to verify it on this platform.
Two birds with one stone and all that. Simple test instructions at:
