Don't be suprised if your patch isn't accepted.  ReactOS is considered a 
dirty reverse engineering project by many, and Alexandre has rejected 
patches using their code before.

The fact that some developers work both on tinykrnl (a self-admitted 
'dirty' reverse engineering effort) and ReactOS at the same time should 
be enough to show you that they're walking close to, or maybe over the 
fine line.

Please don't post ReactOS code to wine-patches again.
