This is the part
The Unix inspiration was the same, but everything worked differently - and the impression was that FreeBSD was distinctly more mature, less chaotic, more focused. A magnificent cathedral - a form then widely criticized in the circles I moved in - but one that had certain undeniable virtues. Back then I compiled the entire system from source, and I noticed right away that performance was better on that hardware than Linux had ever been. Not only that: Linux would overheat and produce unpredictable results - errors, sudden shutdowns, fans screaming even after compilation finished. My Linux friends continued to insist it was a “hardware problem”, but FreeBSD handled the load far more gracefully. I could read my email in mutt while compiling, something that was practically impossible on Linux, which would slow to a crawl. The fans would settle within seconds of the load ending, and the system felt genuinely more responsive. I never experienced a crash. I was running KDE on all my systems at the time, and the experience on FreeBSD was noticeably superior - more consistent and steady performance, none of the micro-freezes I'd come to accept on Linux, greater overall stability. The one drawback: I compiled everything, including KDE. I was a university student and couldn't leave my laptop in another room - the risk of an "incident" involving one of my flatmates was too real - so I kept it within arm's reach, night after night, fans spinning as KDE and all its applications compiled. At some point I figured out exactly how long the KDE build took, and started using it as a clock: fans running meant it was before four in the morning. Fans silent meant I'd made it past.

ETS table races. Process A reads a key from a public table, decides to update it, but Process B modifies it between the read and the write. Classic check-then-act, also known as TOCTOU (“time of check to time of use”). ETS explicitly documents that table traversals provide no snapshot consistency: concurrent inserts during iteration can cause keys to be missed or visited twice. Individual key operations are atomic, but multi-key operations are not.
