Where did you find (so quickly) that MoveFileEx is not atomic on Windows?
On the page where you gave me the link. To be more precises: I could not see that atomicity would be guaranteed. To quote the part of that page which I believe to be relevant: 
1499:   /* CRT is buggy on sharenames, so make sure it really isn't.
3259:win32_rename(const char *oname, const char *newname)
3314:   /* if newname exists, rename it to a temporary name so that we
3348:       retval = rename(szNewName, szTmpName);
3355:   /* rename oname to newname */
3356:   retval = rename(szOldName, szNewName);
3360:       /* ...and rename succeeded, delete temporary file/director
+y */
3365:           (void)rename(szTmpName, szNewName);

So, the renaming is win32_rename is just forwarded to the rename() function, and I couldn't find anything which would guarantee us that this would be atomic.

I am willing to believe that this 'rename' will work atomically, if experienced Windows developer tell me so. It's just that I couldn't see this from the documentation.
