Holding xenbus_lock even across kernel transactions is undesirable if 
we can avoid it, I think. Remind me again why mux/demux is harder or 
more code than spawning multiple pages per domain? Both approaches 
require extra code to be written after all, and it's not clear to me 
that the extra code required in xenstored for mux/demux is very much or 
particularly tricky to write.
