We could return the error for consistency, but we really don't expect this to fail. We know
the target file exists, so the `rm` failing would be a consistency error.

, but I think it should be part of this patch because in any cases we should not use the data
of a `Try` object before making sure it has no error. Or can we just merge this patch and
r66706 into one patch since they are closely related?

I want to keep these two patches separate because it makes it a lot easier to reason about
the changes in behavior. I've added a `CHECK_SOME` to this patch to preserve the original
behavior (until the next patch).

Not in any new ways. Previously an I/O error creating the directory would cause the crash
there. I didn't want to silently drop that error, so we would now crash here instead. There's
sometehing fatally wrong if we can't write the checkpoint successfully.
