Thinking more about it, it might be related to timeout, and/or it might 
be: If xenstored has decided to not answer you, your thread is dead in 
the water, because you end up stuck in kernel land forever (wait not 
interruptible aka D).
(It might have been related to historical reasons, however it could 
still be happening in the unlikely event of xenstored dying)
