That link points to the top of that document. Were you thinking of <http://developer.apple.com/documentation/Cocoa/Conceptual/Multithreading/articles/ThreadIntro.html>? That says:

Threads and run loops are tightly entwined entities. Many simple threads do not use the run loop and simply execute the code in their entry-point function. However, if you want your thread to remain running so that it can process requests at a future time, you need to start the thread’s run loop.

When I create a pthread, is a new run loop created, and is
the pthread associated with it?

Yes, to both questions. The confusion might be that the run loop isn't automatically _started_ when the thread runs. That can be done with CFRunLoopRun after attaching at least one run loop event source.

HTH,
