Not at all.  There's a pile of performance work that needs to be done, 
both native and Xen.  I've been addressing it in an ad-hoc, time-sliced 
way so far, but I haven't had the chance to concentrate on it as I'd 
like to.  Once I get all the basic stuff off my plate I'll be able to 
actually focus.

Besides, its not really the sort of "incentive" that I respond to; I 
find it demotivating because it carries the presumption that I won't do 
"the right thing" without some element of coercion.  It's not like I 
don't already do a fair amount of generally beneficial kernel work.  If 
you think I should direct my attention in one direction over another, 
I'm happy to take suggestions.
