We don=E2=80=99t completely understand the = problem, but backing out r273272 avoids the problem, though it=E2=80=99s = suspected that there=E2=80=99s a bigger problem. r273638 in HEAD backs out everything suspect, and = we=E2=80=99ve been running for several days now with no problems with it. I believe = that it=E2=80=99ll be committed to 10-STABLE in the next day or two. Scott
