* process.c (forked_child): new variable.

  (before_exec): don't call rb_thread_stop_timer_thread if
  forked_child.
  (after_exec): reset forked_child after rb_thread_start_timer_thread.
  (rb_fork): set forked_child just after fork in child.

* ext/pty/pty.c (chfunc): extracted from establishShell.
  (establishShell): use rb_fork.
