I have some monitoring capabilities set up in Xen
and when that is triggered, I want to notify the DomU
to take some action.

Example: If a certain part of memory is touched, Xen 
sees that and wants to inform the DomU of this.

So, all I need is to set a bit somewhere that can
be constantly polled by the DomU (waiting for it to flip)

Thanks,
-Brian

What do you want this 1-bit of information to achieve at the other
end... 

Without actually knowing what you're trying to achieve, it's kind of
hard to answer the question.
