Hi all, The documentation for the multiprocessing module claims: | Note that the start(), join(), is_alive() and exit_code methods | should only be called by the process that created the process object. Two problems with this description: 1. "exit_code" should be spelled "exitcode" 2. exitcode is an attribute of the Process class, not a method as claimed, since the underlying method is decorated with @property Also, aside from the above documentation issues, if it is true that it's not safe to query the exitcode from a separate process, should the exitcode property method include a check like so: assert self._parent_pid == os.getpid(), 'can only test a child process' since start(), join(), and is_alive() all perform this check?
