Rebased due to collision with recent configure.in adjustments.  I also
wrote a commit message and retested with create-dsm-test.patch (from
upthread).

So, do we want this patch?  It's annoying to expend cycles doing this,
but it only really hurts if you allocate a lot of DSM space that you
never actually use.  If that ever becomes a serious problem, perhaps
that'll be a sign that we should be reusing the space between queries
anyway?
