As far as I can tell, the current delay *works*. It just doesn't
necessarily work the way most people expect it to to work. Kind of
like, hmmm, shared_buffers? Or effective_cache_size? Or
effective_io_concurrency?
And I still think that having this kind of a delay option will give us
invaluable use feedback on how the option *should* work in 9.1, which we
won't get if we don't have an option. I think we will be overhauling it
for 9.1, but I don't think that overhaul will benefit from a lack of data.
