+.SH BUGS
+.I Nice
+and
+.I nohup
+are particular to
+.IR sh (1).
+If you use
+.IR csh (1),
+then commands executed with ``&'' are automatically immune to hangup
+signals from the controlling terminal.
+There is a builtin command
+.I nohup
+which provides immunity from terminate, but it does not
+redirect output to
+.I nohup.out.
+.PP
+.I Nice
+is built into
+.IR csh (1)
+with a slightly different syntax than described here \-
+``nice +10'' nices to positive nice, and ``nice -10'' used
+by the super-user nices to negative priority.
