>From "Programming with POSIX Threads" [David R. Butenhof]:

p.197-198:
  ... Avoid using fork in a threaded program (if you can)
      unless you intend to exec a new program immediately
  ... Pthreads does not "terminate" the other threads
      in a forked process. ... They simple cease to exist.
  ... The state of mutexes is not affected by a fork. If
      it was locked in the parent it is locked in the child!
