As described in a comment, it's possible to implement this entirely on the
server side. I found it to be difficult and fragile due to the difference in
structure size between 32-bit and 64-bit processes, and elected to simplify the
server's job by handling that in ntdll. I'm open to moving the whole ioctl to
the server, though.
