I'm not convinced it's actually a roll-over problem though. Piece of trivia I once picked up, that as it was orignally released, Windows NT would reliably hang every 40 days (f it ever lasted that long). Seems that NT was keeping uptime in terms of milliseconds, with no rollover, which it would do anyhow every 40 days.
