--- Comment #2 from Rui Ueyama <ruiu at google.com> ---
If you are using lld on a half-broken disk, it is likely to slowdown or hang
because lld uses mmap IO. Since mmap IO doesn't report an error to a process,
there's no way to detect it and abort a process. I don't think this is
something we can fix -- this is more like a limitation of the POSIX API.
