Attached is the patch.  Interestingly, on my single-socket
two-core recent-vintage Intel processor, this patch reports
a max skew of >13 usec, much higher than the values I'm
seeing from "xm debug-key t".  I wonder if this is due to
a mistake in my patch (though I don't see it) or if the
various stime error corrections are not converging as
expected, resulting in a broader stime skew between
processors than expected?
