Cleaning out broken tryPickleOnAllContents3

@keckler @drewj-tp Do you guys know of any reason why this would be a bad idea? The function looks broken to me.

(I have obviously done all the downstream testing I can, and it all passes.)

I don't really know anything about that function. I have never used it, or even knew of its existence.
