> Check that the path through sort that notices low memory conditions and
> causes the sort to spill ("out of memory condition management").
> Also check to make sure we handle queries and fragment failures properly
> under these conditions.
> "hashjoin, hashagg, and topn use large amounts of memory,and may be unable to
> complete if their memory needs can't be met; for all others, the idea is that
> they can complete if they get their reservation"
