But din't we need sime infrastructure for that page in place anyhow? I am quite sure that e.g. WinHelp() in WinNT uses that page.
Most of user32.dll in NT uses it, that's how it communicates with the portions of user32 that are in the kernel. But we are not going to run the native NT user32 anyway, and our user32 does things differently.
