The problem with that is that it is really equivalent to just
reducing the sensitivity of the test to sensitivity^3 (if, e.g, the
test will pick up anomalies with stochastic probability of less than
alpha as is, making it retry three times really just reduces that
sensitivity to alpha^3).  I think the right answer here is to find
out why the test is failing with higher than, say .001 probability
and fix the underlying problem.  If the test itself is too
sensitive, then we should fix that.  Then switch to a fixed seed for
the released code, reverting to random seeding when the code is
under development.
