Chapter 6.1 of Butenhof's pthreads book deals with this, and well, it is a mess.  According to him only the calling thread exists on return from fork() in the child process, but the other pthread *states* (mutexes, conditions, data keys, etc.) are replicated as well.  And I'm sure the details vary from system to system.
This is the chapter's first sentence: "Avoid using fork in a threaded program (if you can) unless you intend to exec a new program immediately."
