Given that Kris Moore has stated in this thread that he's not concerned
(on behalf of pc-bsd) if this functionality doesn't get backported to
RELENG_6, I'd be curious to hear how hard it would be to implement this
same functionality with sigqueue(2).
FWIW, I'm _all_ for improving our ability to run Wine (and any other
functionality that will help us be a better desktop OS). If we can get
Wine to the point where it's useful and reliable for day to day stuff,
I'll be one of the people running it day to day myself.
