Log Message:
PR bin/48875 - avoid holding (replaced) file descriptors open when running a
command in the current shell (so they can be restored for the next command)
in cases where it is obvious that there is not going to be a following
command to use them.   This fixes the problem reported in the PR (though
there are still plenty of situations where a FD could be closed but isn't,
we do not do full fd flow eveluation to determine whether a fd will be
used or not).

This is the change that was just committed and then backed out again...
