That was not a part of my patch, although I remember that you mentioned
that previously and I thought it could be a good way to mitigate a
problem if it ever came up.
However, the tests I did didn't show any problem there. The tests were
somewhat noisy, so perhaps I was doing something wrong, but it didn't
appear that looking at the VM page for every update was a bottleneck.
