A friendly tour of process memory on Linux

Instruction pipelining and this is exactly why I wish we still have the time to go back to "it is exactly as it is", think the 6502 or any architecture that does not pretend/map/table/proxy/ringaway anything.

That, but a hell lot of it with fast interconnect!

... one can always dream.

I'm curious how this dream is superior to where we are? Yes, things are more complex. But it isn't like this complexity didn't buy us anything. Quite the contrary.

Totally depends on who "us" and isn't. What problem is being solved etc. In the aggregate clearly the trade off has been beneficial to the most people. If what you want to do got traded, well you can still dream.

The article is essentially describing virtual memory (with enhancements) which predates the 6502 by a decade or so.
