Neat.

It seems like it's special-purpose enough to warrant a place in among
the examples, which are currently checked in at
.../testsuite/systemtap.examples/, as opposed to the tapset proper.
The scripts and a README could go into a new subdirectory.  For
cataloging the scripts, a brief ".meta" file should accompany each
end-user (as opposed to tapset) script.  They could each have a
"test_check" field to compile-test the scripts.  (A test_installcheck
field to actually inject faults into a running developer system is
probably not appropriate. :-)

Please place proper copyright notes and GPLv2+ license terms on the
files; then we can package them.
