Coincidentially, last night, and I'm not pulling your leg! But to be fair that's the first time in much more than a decade. I don't normally work with such huge files and this was one very rare exception. I also nearly crashed my machine by triggering the OOM killer after naively typing 'vi file' without first checking how large it had become. I'm working on a project that I probably should run on a more serious machine but I don't feel like moving my whole work environment from the laptop that I normally use.
