This turns out to be trickier than I first thought, because there's very little shell infrastructure to help do it. It will be a while before I design and implement a solution.

fd leak with {fd}>
Repeated executions of: { echo $fd ; } {fd}> /dev/null
will emit different numbers, indicating that fd is not closed when the

{ echo $fd ; eval exec "$fd>&-" ; } {fd}> /dev/null
