Oh, I haven't seen that issue. (Notice "made me reconsider" from ryao). But pagecache is still something that isn't fixable (you can't disable VFS pagecache, it's too intertwined with the whole I/O system) - I don't see a way to implement ZFS "linux way" considering things like block sizes bigger than one page being antithetical in linux.
