Hi ,

  I am testing Python 2.5 on HP-UX 11iv3 using gmake test , while testing the test  test_mailbox.py is hanging . 

  when tried to track the problem i came to know that
in the function 
      if pid == 0:
            # In the child, lock the mailbox.
            self._box.lock()
            time.sleep(2)
            self._box.unlock()
            os._exit(0)

        # In the parent, sleep a bit to give the child time to acquire
        # the lock.
        time.sleep(0.5)
        try:
            self.assertRaises(mailbox.ExternalClashError,
                              self._box.lock)
        finally:
            # Wait for child to exit.  Locking should now succeed.
            exited_pid, status = os.waitpid(pid, 0)

 after forking the child , child is not returning status to the parent while its waiting for the return status. 

  which part of the Python functionality is checked. 
 
   Please assist me to solve this.

Thanks in advance ,
shashi

Can someone with an HP-UX box please see if this is still a problem with currently supported versions of Python.
