This is an incredibly fascinating and detailed account of a truly peculiar bug! The way you traced the issue through logs, system behavior, and even diving into assembly-level debugging is impressive. It’s amazing how such a seemingly simple problem—like an infinite loop in `ps`—could stem from such a nuanced edge case involving process termination timing. The historical context about QNX and its transition from open-source to corporate ownership adds a layer of depth to the story, highlighting how changes in software ecosystems can impact debugging and development. Your persistence in compiling the old `ps` source code and reproducing the issue is a testament to thorough debugging skills. This kind of deep dive into system-level behavior is both educational and inspiring for anyone working in firmware or low-level software. Great read!
