I didn't fully understand the (subtle) semantics of open() with O_CREAT and the mode. It expects the file to first be create/opened with the given flags, and after that the mode is set on the file. So permissions checking of the flags against the file's mode can only take place if the file already exists. I've pushed a fix to the wip-3346 branch.
