Are you sure you have the right line numbers? The cygwin version of lib/mkdir-p.c is patched in coreutils-5.97-1; but even the upstream version takes great pains that this is not a race - yes, the directory can be created between the time it is statted and the mkdir, but the mkdir takes this into account by trying to chdir into the directory on failure, before giving up with an error message to the user that the file exists. I will need a stronger argument to believe that there is a race, in which case, the upstream maintainers would probably like to hear it too. - -- Life is short - so eat dessert first!
