Some update on regression -rt stap test that It looks like I fixed
most of deadlock specific bugs in stap specific -rt mode.. with
obvious addition of more -rt stap patch to show up in v3 version
soon.. Running one last time regression stuff with more load on 12
core Ivybridge machine before flashing the patches.
Thanks Frank for autotest pointers.
