Well, I added support for NetBSD in a piece of software, in the critical part it was using
mostly the ptrace(2) interface... it was a real mess, because the same kernel and different
CPU on some platforms can result in different APIs.. so I can understand why people
prefer to have the mess abstracted in a building block and not implementing it locally.

I'm not experienced in runtime development, so I cannot judge whether all that is needed:

Can you propose an alternative to making libunwind work on NetBSD?

OK, For now it's not a critical feature and my runtime doesn't make use of it.
