Also, I notice that xl does not yet have any machinery for detecting
infinite guest reboots.  I suggest that we take this opportunity to
invent a new mechanism for that, and it could be configurable.

xl could record the times of the last N restarts in an array, quite
easily, and spot when there have been more than N restarts in time T
(for default values of N=5 and T= fifteen minutes, perhaps).

Ian.
