Gary Nebbett's book "Windows Nt/2000 Native API Reference" in the section C
"Exceptions and Debugging" provides a pseudocode for KiDispatchException
(page 439, Example C.1), and it does exactly the same thing as the patch
above. *But* it does it as a very first thing after getting the context and
before sending the debugger event.
