It was Peter Wemm.  I may be misunderstanding just what he did--trying
the 4.0 driver was just one several experiments he proposed and
performed.  And saying that it "worked" is provisional; two days of
testing strongly suggests that it reduced the problem with 3.3 to
acceptible levels for my application.  Is it truly a "fix?" I don't
know.
