A background job executed from a login shell is related to the
invoker's terminal.  A shell script similarly.  A background job
executed from a shell script is not.

Example:

Put the line

	tty > jnk

in cmd.

When you run cmd or master it works fine.  From bgmaster it says "not
a tty"

Now, "rm" has a check in it to see if you are a terminal (isatty()).
If not, it runs as if the -f flag was specified.
