I hate to fall so neatly into this pattern of incredulity-then-ridicule
that you perceive here, but I don't think I've ever implemented a hash
table where I stored the address part of hash keys, except when I didn't
care about memory footprint. It didn't occur to me that something that
obvious could be your "big secret".

Funny, I view exactly this kind of reaction ("cannot-work" before I give
the explanation, "oh-yeah-it's-simple!" after) as the perfect one, since
the best ideas always achieve incredible things by simple means.

While I found quite a few interesting contributions among the 60+ posts
of the last 24 hours, nothing of what you "disclosed" so far was in any
way, shape or form news to me. Good practice, certainly, but not the
earth-shattering revelations you seem to think they are. Over and out,
