And common javascript engines. Turns out a lot of interpreters hide bits away in what they precieve to be unused address bits. Its one of those lessons that everyone seems to be constantly relearning. Address spaces grow. One of my first "real" jobs, when this topic came up a very senior person said something to the effect. We continue to find ways to use up one of those bits roughly every year. Moving from 32-64 bit VA's is going to get beyond the end of my career but someone will have to deal with it in the future. So its a little slower than 1 bit a year, but everyone is adding a few more bits (52/56/etc) because there are actual commercial computer systems with a few tens of TB of ram today. If persistent memory ever becomes a thing, someone _WILL_ want to mmap their multi PB storage cluster, and then there will be a scramble for more address bits.
