I don't know how many people use unit-threaded
(https://github.com/atilaneves/unit-threaded) for their tests,
and of those how many use Arch Linux, but for anyone else there
for who that applies, I added a dtest
(https://github.com/atilaneves/dtest) package to the AUR:

https://aur.archlinux.org/packages/dtest/

I also did it to learn how to create Arch packages.
