I see. I should check again because things can change but my app is performance sensitive and when I checked last it seemed to give myself a boost since I was writing to the memory so quickly.
One of the reasons why I use MAP_GROWSDOWN is because it gives me a page guard. Your link mentions/implements a page guard. Well done
I tried my complicated app for fun removing the MAP_POPULATE flag. I get an assert because it seems like mmap didn't align the pointer to 4K. I don't need this to work I was just playing around with it
As you wish. I've just pushed a change removing the restriction on MAP_POPULATE. https://github.com/jart/cosmopolitan/commit/ccd057a85daf0d2d... Now that we have -n (maximum niceness flag) I doubt anyone will object. If your app is public and you're building it with Cosmo, then I look forward to the opportunity to see it someday.
