Thank you Neal (and sorry for calling you "Neil" before),
The fix to the prctl test will appear in 0.8.0_b2 (probably later
tonight).
The ptrace test failure is still a mystery to me. I know the fc8 and
fc9 kernels replace the ptrace implementation from the kernel.org
kernels with one written in terms of Red Hat's "utrace". However, I
cannot pin down what the difference is between the two that leads to the
BLCR test failure. It is possible that there is a utrace bug, but I am
not holding my breath.
