Just to emphasize the point: about a month ago I spent 3 full days
trying to track down what I thought was an ugly reference-counting
error on domain destruction, but turned out just to be xend running in
the background and messing with things behind xl's back.  That's what
prompted us to put in the check. :-)

Perhaps the warning should explicitly mentioning disabling xend as the
best solution?
