I've re-run the test few times with the system no longer loaded, and
it passed.  I he re-run it one more time with the system under some
load again, and this time the test was skipped!

    timeout-group.sh: skipped test: timeout returned 142. SIGALRM not handled?
    SKIP: tests/misc/timeout-group.sh

The detailed log of the skip is here below.

HTH,
  Stefano
