"The SystemTap developers do seem to be interested in these
reports, which is a good sign. There are other things happening in
the SystemTap arena, including the release of version 0.7 on July
15. This release adds a number of new features and tapsets, and a
substantial set of examples as well. Meanwhile, Anup Shan has
posted an interesting integration of SystemTap and the fault
injection framework, allowing tapsets to control fault injection
and trace the results."
