The reason it's still here is that Andres expressed a concern that
there might be more than meets the eye in this. What meets the eye
is that PANICing on file-not-found is not appropriate here, but Andres
seemed to think that the file not being present might reflect an
actual bug not just an expectable race condition [1].
Personally I'd be happy just to treat it as an expectable case and
fix the code to not PANIC on file-not-found.
In either case, it probably belongs in the "older bugs" section;
nightjar is showing the same failure on v11 from time to time.
