Hmm, as a test, I tried adding @Timeout(millis=100000) to
LuceneTestCase, ie 100 seconds, which I think should not trigger on
any core tests today.

That should then apply to all subclasses of LuceneTestCase right?  Ie
all tests will be aborted after 100 seconds...

But, something is wrong: I get lots of quick (ie much less than 100
seconds) failures like this:
