Something wrong with this patch ?

I assume there's something wrong with my patch ?
I've did some research lately on how 32 Bit programs interact with 16Bit
windows. This patch doesn't help if a SendMessage was sent from a 32Bit
application because it gets dispatched from the 16Bit thread. So
NtCurrentTeb doesn't work. At least it fixes uncaught WM_USER messages
in the current process.
