I'm unsure about that. I liked the original idea of only trying mkdir_p
when plain mkdir() had failed with ENOENT. I am not convinced your
proposed patch will behave desirably under all error cases. In
particular, mkdir_p seems rather dependent on knowing just which errno
codes will get returned --- which is okay for its heritage as BSD-only
code, but how well will it port? Better to only invoke it when we have
reason to think it can help.

We have a whole development cycle to shake these issues out. Don't
panic.
