We all agree on that being a "worse case".
So what's the true fix? Why can processes use 30GB of swap on your
machine at all? My swap is only 8GB and my RAM is 8GB as well. Should'nt
we limit RAM usage to a sensible value such as 4GB in nixos-rebuild
script to protect against this case of failure? Calling limit or such
would be the easiest thing to do ?

Seriously: If you allow 30GB of swap you should consider closing some
apps in most cases because swapping is slow.

That would fix the "annoyance" for you and everybody else. We all don't
want this to happen (especially not on servers). Until now I thought
running "nixos-rebuild build" and walk away would be safe enough
compared to "test".
