this is one of a dozen systems upgraded fom 9.3-stable to 10.1-release
p10 using a recipe in https://wiki.rg.net/wiki/FreeBSD9to10.  they all
show the same symptom.

it was consistent for all of them.  i was waiting for p11 to see if it
would fix it.  it did not, at least for this first system i tried.
