There are still supported i386 CPUs that don't support HLT and
would recursively fault here.
The HLT has been supported since 8086. However, it was broken in some
early 486s (not 386s); that's what the test in the kernel is for.
I don't remember what the failure mode was, though; didn't think it was
recursive faulting.
