well yes, "very probably" is pretty good odds i think. :p

more seriously, it depends from which perspective you're looking at the 
dom0 restart problem. But according to previous experience during 
oxenstored development, i'm pretty sure that oxenstored would cope and 
that most of the problems are elsewhere in the stack. moving oxenstored 
to a stubdomain is almost orthogonal (roughly 89 degrees.)
