Let me see if I understand this:
-rt mode: This is your patched systemtap running on a rt kernel
non-rt mode: This is your patches systemtap running on a regular,
non-rt, kernel.
Is the above correct?

What's odd here is that the number of unexpected failures is higher on
the non-rt kernel. I would have expected the other way around.
