Paul, could you please look into this?
I am taking a look. Sigh, what a mess this code is; even the proposed fix has a TOCTOU bug.
The simplest fix I can see is to enhance make-directory so that it returns t if the directory already existed and PARENTS was given, nil on any other successful return. This would require changes to Tramp to avoid races there. I plan to post a proposed patch for comment.
