rustix does not currently expose the _exit system call as far as I can tell. This would be useful in at least two contexts:
- On the child side of a
fork (which is also missing right now but I trust it's already on your list of things that need to be added)
- In
#[no_std] crates that nonetheless have the kernel available (e.g. the various projects trying to make it possible to write Rust programs that do not use a C library).
