I had in mind some kind of reminder, like a fixme to use it in more
places, consistently, but...

... I don' think it's bugus. I googled a bit and it seems a security
hazard. I'm a bit worried, even if probably it doesn't matter much for a
test. As I said above, we are looking for something solid, to be used
also elsewhere in the testsuite, in the future.
