* * debug.cc (add_handle): Issue warning on attempts to add the same handle moreChristopher Faylor2000-10-171-4/+10
| | | | | | | | | | | | than once. * fhandler_tty.cc (fhandler_tty_slave::open): Protect some handles. (fhandler_tty_common::close): Use proper name when closing handles. (fhandler_pty_master::close): Don't close to_slave or from_slave since they've already been closed earlier in the function. * sigproc.cc (proc_subproc): Don't protect vchild->hProcess. Expect that the caller will do this, instead. * tty.cc (tty_list::terminate): Use proper name when closing handles. (tty::make_pipes): Protect some handles.
