As of now, I find `earlyoom` is better choice than `nohang` for three reasons:

1. It comes preconfigured: https://build.opensuse.org/package/view_file/openSUSE:Factor...

2. Packaging adoption: https://repology.org/project/earlyoom https://repology.org/project/nohang

3. Written in C and unburdened with tangential features like desktop notifications, the daemon's process takes very little amount of memory.
