Use of std::process::abort is potentially unsound

[nagisa]

std::process::abort might fail to terminate the program if the signal is caught and the handler longjmps away. While longjmp is a poorly supported feature in Rust, it is nevertheless something that is valid to do.

Would switching back to exit be sufficient to resolve this? If I'm reading manuals properly, attempting to longjmp from a place that can interfere with exit is undefined.

[Sgeo]

Discussion in the Rust discord makes me believe longjmp is currently considered to be usually unsound in Rust.

Might be worth keeping an eye on rust-lang/rfcs#2625
