* fhandler.cc (fhandler_base::open_with_arch): Call close_on_exec last to avoid
setting close_on_exec for archetype.
* fhandler_tty.cc (fhandler_pty_master::setup): Protect {from,to}_pty handles.
Use consistent naming in debug output. Use inheritable handles and...
(fhandler_pty_master::fixup_after_fork): ...avoid duplicating handles here.
(fhandler_pty_slave::open): Don't set close_on_exec flag here.
