$ grep \"Timed out\" \$(find -name \*.out)

It is possible to re-run a single test with enlarged timeout with \"TIMEOUTFACTOR=<factor> make test t=<test name>\". For example, \"TIMEOUTFACTOR=10 make test t=nss/tst-nss-files-hosts-multi\" will re-run nss/tst-nss-files-hosts-multi with ten times the original timeout.
