That's a very strange response. This is an article about Linux specifically. The author tags the article with Linux and mentions that it's part of a series of articles about Linux. It's not in and of itself a bad idea to have articles that specialise in a specific unix flavour.

Secondly, SIGABRT will cause the process to abort and dump core, will it not? That would give you a userspace stack trace (if you load the core into a debugger) whereas this is how you get the kernel-side stack trace of a still-running process.

I don't know of a way to get the kernel stack trace of a process in a cross-platform way. Is there such a thing?
