Whoa, that's a good one.

The difference seems to be the difference between:

  dash -c 'exec 1>/dev/null; echo closed 1>&2; exec 2>/dev/null; read'

and

  bash -c 'exec 1>/dev/null; echo closed 1>&2; exec 2>/dev/null; read'

Dash prints "closed" and exits immediately with error code 2.  Bash
prints "closed" and waits for input from the "read".

Are we relying on non-portable shell behavior here?
