	pdksh can become wedged when ^Z is typed while executing a backquote
	expression interactively.

        $ sleep 600 `jot 1000000`

	Type ^Z while jot(1) is running.  jot(1) will be suspended.  ksh will
	now ignore ^C.  The only way I found to wake it up was to `kill -9'
	the jot(1).

        None supplied.
