@andrewrk I am a complete idiot when it comes to the real technical discussion here, but I've been watching the development of snmalloc from a distance which may very well and up landing in FreeBSD to replace jemalloc. I haven't seen any projects actually adopt it elsewhere. If it would be beneficial for Zig that would be neat. Don't mean to derail your R&D project here, just felt like a suitable place to mention its existence.
