Ever read gdb output and you just kinda get a headache because you have to infer what a thread is by reading the stack trace? It's not hard, but we could also just never have to do that again, which is also not hard. Sample: (gdb) info thr Id Target Id Frame * 1 LWP 3719283 "nix-daemon" 0x00007e558587da0f in accept () from target:/nix/store/c10zhkbp6jmyh0xc5kd123ga8yy2p4hk-glibc-2.39-52/lib/libc.so.6 2 LWP 3719284 "signal handler" 0x00007e55857b2bea in sigtimedwait () from target:/nix/store/c10zhkbp6jmyh0xc5kd123ga8yy2p4hk-glibc-2.39-52/lib/libc.so.6 The API design for this is forced by the macOS pthread_setname_np only being able to change the current thread's name, but if we just conform everything to that, it works everywhere.
