With the understanding that somebody had complex logic in the equivalent of a signal handler in linux, then i am not sure this bug is so fantastic after all. I have signal handlers so high on my danger zone that i do not recall ever coding any. If I am in a sigabrt or sigsegv i hope i die as cleanly as possible, so that a core dump is useful. No wonder he needed kernel level development.

No, absolutely not. It just illustrates the problems that obviously insane code can lead to and why we call it "insane" in the first place. But it was still a fantastic read following him on his journey from "huh, that's odd" to "I had to use kernel-level debugging to find out they were ~~throwing from an APC~~ using APC." Imagine how much he could have achieved in those five days if he had just unfucked obvious bug magnets proactively without first painstakingly proving that they were really manifesting as bugs, and how.
