I was hoping for some success stories ;-)
I think Peff (who I stupidly managed to not Cc in the series, there's
another git-send-email usability issue there) asked for the third from
the tip, which lets you run valgrind only on a certain test. (For
example, if you've already had two coffees while your computer found out
which test it was, this is a much faster way of seeing if the failure
disappeared.)
So one obvious way of going forward is cooking this for a while and
seeing whether people find the one-test-only or the massively-parallel
feature useful (or maybe both).
[To anyone who just reads this, but did not see the original series, I
should also point out that this only applies within a tNNNN-foo.sh test
file. You can already parallelize a full valgrind test run much better
than the above.]
