I'd really want real performance numbers. I don't like the "remove it
because I don't like it". I want real numbers for real loads before I'm
really interested.
Last time this came up, the logic behind wanting to remove the zero page
was all screwed up, and it was all based on totally broken premises. So I
really want somethign else than just "I don't like it".
Sorry. In the absense of numbers (and not just some made-up branchmark:
something real - I can _easily_ make benchmarks that show that ZERO_PAGE
is wonderful), I'm not at all interested.
