I like vibe coding but I am sceptical that a vibe coded runtime in Rust would be as awesome as the Go runtime which is written with deep expertise of Unix software and threading and many low level details that are subtle and do depend on global properties of the code to work flawlessly. It makes sense you can crank out Rust with an LLM if you know what you are doing, but if you want a GC type thing or preemptive scheduling across an N by M threading model, then you are competing against some very good code.

Go has no mmap(), import a 3rd party dependency for that and you'll get a segfault the very second you do a mistake.
Python has an mmap module which will catch many memory errors and present them as exception rather than causing a CVE.
I don't agree with the parent comment, but mmap is exposed (low-level) in the standard library and there's a high-level wrapper in x/exp. You need to be careful with mmap no matter where you're using it.
What Go mmap CVE were you thinking of?

Every time you see "segmentation fault", that right there is a CVE.
