Changes of Release 1.1:

• Now works on systems with more than one CPU socket.
• Now works on systems where the Linux kernel assigns non-consecutive core ids.
• Privileges were not dropped as expected after initialization when running as non-root user.

• Better error handling
• More informative debug output with -d
