Thanks, Bill!

Feeling a little stoopit here.  So p(false failure) = 1 - dbinom(0,
100,.001) = 0.09520785 ~ what we are observing.

The p-values reported on failure are generally near the boundary.  I
guess the alternatives are to reduce the sensitivity or to disable
the tests.  I am OK leaving as is as long as others don't mind the
noise.
