I don't believe so - this was a bug, not a feature - but why not just
close the standard I/O descriptors when you start the program, as I
suggested in my first reply?

If your script has a command like

cobrun foo

just change it to

cobrun foo <&- >&- 2>&-

This assumes your script is a ksh script; the syntax for other
shells may be different. (It might also suffice to redirect
standard I/O to/from /dev/null.)

In ksh, you can close or redirect standard I/O for the script
itself and any programs it starts all at once by making the
first command

exec <&- >&- 2>&- # close standard I/O

or

exec < /dev/null > /dev/null 2> /dev/null # redirect standard I/O

The latter is probably safer, as some programs assume that the
first three descriptors will be open. You might also want to
redirect stdout / stderr to a file to preserve any information
the script or its children might try to display.

Sounds like you have a version with this bug, then.
