This removes the FIXME suggesting that mkdtemp should rely on the default umask, because that would make it unusable for making a secure work area in a world writable directory (have to assume that other users have created files, directories, hard links, etc. in your directory). The POSIX mkdtemp function creates a directory with 700 permissions to avoid this problem.
