Hello, exit(3) and wait(2) both mention that only the least significant 8 bits of the 'status' argument are returned to the parent process; _exit(2) does not mention that.
I'd like to add the following note here (see attached diff). Arguments against: _exit(2) references wait(2), so users could in theory dig into that there and find it mentioned somewhere a few pages down. Arguments for: makes it much more obvious; OpenBSD has similar wording in https://man.openbsd.org/_exit. Any objections? -Jan
