I see it daily when running xm-test. Yesterday, however, I saw it for 
the first time with only one guest domain running. Because there was yet 
another problem
(http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=390), I could 
not tell whether they were related--I now believe they are not.  At any 
rate, that is probably the only other time I've seen it, and I have not 
been able to replicate that situation. Xm-test recreates it 
consistently, though.
