I don't have a strong feeling on it. It is only one extra line of
code to make the hash table context a child of CacheMemoryContext
rather than TopMemoryContext, but since we've been doing it this way
for so long, there's not any real clear value in changing it. Though
it does make me wonder whether there's any point in retaining
CacheMemoryContext at all.
