(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.] -- Thomas Rast trast@{inf,student}.ethz.ch
