If you read the rentry you'll see that both of them were working on an issue that l29ah raised, along with other users. jart's work was on something that didn't end up making it in, the malloc() approach. slaren is the one who wrote the code in the commits I linked to, and that's the code that was adopted. You can (and should) do a comparison of the mmap code and see. What I wrote about the version change, magic number, WIN32, etc., is all true too. As is the haste with which the new PR was made, leading to the recent pushes to revert due to swap thrashing and anger over false and rushed claims about "miracle RAM reduction" etc.

In fact, if you read the thread you linked to, you'll see this for yourself too, no reentry required. There's nothing actually objectionable or "repulsive," as jart put it, in that renetry, with an exception of the "r word" being applied to a proposed technical solution.

Your interpretation is incompatible with what we see and the clear timeline. The social media bragging, the second PR, etc., are further evidence. I hope whatever anger you had going into this has abated to the point where you can now actually judge the evidence.
