I did some more googling to try to understand the issue.

First, there has been a similar discussion on FreeBSD mailing-list. It might be
of interest :

http://unix.derkeiler.com/Mailing-Lists/FreeBSD/hackers/2007-02/msg00068.html

I also read The Open Group Base Specifications Issue 6, IEEE Std 1003.1, 2004
Edition, and more specifically chapter 2.9 (Threads). It is available at
http://pubs.opengroup.org/onlinepubs/009695399/functions/xsh_chap02_09.html

About Thread ID (2.9.2), I read :

"A conforming implementation is free to reuse a thread ID after the thread
terminates if it was created with the detachstate attribute set to
PTHREAD_CREATE_DETACHED or if pthread_detach() or pthread_join() has been
called for that thread."

To me, this gives credit to the hypothesis that that the lifetime of a Joinable
thread (the default state) lasts until it is joined or detached.
