Looks like The Chromium authors may have disassembled part of the
Windows Kernel in order to achieve this security feature [Data
Execution Protection] under Windows XP SP2. Probably not cool to do
that, but they're clearly doing it for good and not evil, as their
intent (from reading their code) is to make their browser safer under
XP SP2 and prevent unwanted code execution.

I thought it was a no-no to disassemble Windows. Of course, that
doesn't stop malware writers. Wonder what bugs they found.
