Ok, this is getting really annoying, according to my lawyers, I have to
never respond to emails with this in it, and should just delete it.  But
I'll be nice, and tell you all to go fix all of Intel's email system to
never send this stuff out again, it keeps happening over and over and
over and is preventing you from contributing to open source projects.

email is now deleted.
