title: Linux user space threads, kernel threads , lightweight processes
body: <p>I am bit confused with all this enteties and how they interconnected in Linux. "Unix internals" book states that <code>lightweight process (LWP)</code> is kernel-supported user thread, and that kernel doesn't see threads inside processes. Is it stil true for Linux? </p>
  
  <p>As I understand, user-space threads scheduled inside process, by higher level abstraction as <code>pthread</code> library, without kernel's intervention. Am I right?</p>
