Oops, right you are.  I think I meant exec > /dev/null.  IIRC, there
was some sort of shell bug which triggered with closing stdout (>&-),
but redirecting stdout to /dev/null was a workaround.  Not sure if its
relevant here, especially since I think bash was being used on linux.

be using "echo 1>&2" based on what you said above.
