JDK should use O_CLOEXEC when available; faster and less racy than FD_CLOEXEC.
O_CLOEXEC is standardized.
http://pubs.opengroup.org/onlinepubs/9699919799/functions/open.html
Backward compatibility needs to be provided via #ifdef and checking (once) whether O_CLOEXEC works.
All the Unix variants should have very similar changes to their os::open code applied.
