There's an assert in autoconverge that checks that we quit the
iteration when we go below the expected threshold. Philippe
saw a case where this assert fired with the measured value
slightly over the threshold. (about 3k out of a few million).
I can think of two reasons:
a) Rounding errors
b) That after we make the decision to quit iteration we do one
more sync and that sees a few more dirty pages.
So add 1% slack to the assertion, that should cover a and
most cases of b, probably all we'll see for the test.
