It means that if one processes is attempting directory creation and other 
processes are performing other filesystem operations (including directory 
creation, but not limited to it), then directory creation in the first process 
is guaranteed to completely succeed (creating a directory with the desired path 
and permissions and returning 0) or completely fail (returning an error and not 
touching the file system). This is not the case on all file systems and on those 
on which it is, the POSIX API does not guarantee that mkdir() is implemented to 
take advantage of it.
