umask	back to summary
public static int umask(POSIX posix) Joy of POSIX, only way to get the umask is to set the umask, then set it back. That's unsafe in a threaded program. We minimize but may not totally remove this race by caching the obtained or previously set (see umask() above) umask and using that as the initial set value which, cross fingers, is a no-op. The cache access is then synchronized. Todo Better?
