OK. So that confirms kernel bugs. Perhaps you should fork this bug
against the kernel, and hope for the best.

David, can you advise to what extent the results of this whitelist
test could be useful, for example to populate our blacklist? The
number of non-inlined kernel functions is far greater than 963, so
perhaps this default test run just looked at those functions listed by
the various tapsets. If so, one'd need to add gross patterns like
kernel.function("*").call to give the kernel a manlier workout.
