The "nohup" command (used to run a command in the background and get your
prompt back right away) has been changed.  It now enforces the previously
voluntary restriction of running one such command at a time.

Now, you can safely run a second command some time after the first; if the
first has not finished, "nohup" will complain and refuse to run the second.
The correct method for running a command in the background remains:

	% nohup ms -p lpr file1 file2 &

where "nohup" and "&" are obligatory and the "ms -p lpr file1 file2" could
be any normal command.

The ampersand (&) must NEVER be used without "nohup".
