Check commands issued in your login and Xwindows startup scripts are appropriate
for tcsh e.g. supported redirections, and do not depend on a tty e.g.
if (-t [012]) stty...

Thus no job control in this shell.

Class: Mostly harmless. X11 launches an interactive shell behind the scenes to
run your client startup file (.xinitrc). This was done so that you don't have to
add statements to set up PATH in that file. Some shells complain that they're
not connected to a real terminal, but that can be ignored since that shell
instance is not used for anything that requires job control or the like.
