So we have potentially 2 definitions of meatgrinder.
We all agree that "Tomb of Horrors" was something, and that the 3.0 edition of Return to the Temple of Elemental Evil was something else.
If you want to call "Tomb of Horrors" a killer dungeon, because it had frequent deathtraps... that's fine.
You could then call "Return to the Temple of Elemental Evil" a meatgrinder, because it had a grinding aspect (very long) and it was also very deadly.
I'd say that 4E published modules so far are not at all in the "Killer Dungeon" mold, because the point of 4E was that save-or-die effects are gone, and it takes significant effort to kill a character. There have been some good "killer dungeons" as late as 3.5 edition, including the adventure "Crypt of the Devil Lich".

Note that this is called a "meatgrinder" in the review.

I think Crypt of the Devil Lich does a great job in doing what it sets out to do: provide the DM with a 'meatgrinder' PC-killer of an adventure that any PC would be proud to be able to boast that he survived. The numerous player handouts add greatly to the adventure's appeal, and the majority of the tricks and traps in the crypt are very well thought out, with rules accounting for most everything a PC might try.
