I'm actually fine on the whole tripwire thing. Let it just be less
annoying (e.g. our nightly tests produced 50+ Mb of logs per run filled
with these outputs; that pretty much blowing up the entire continent
triggered by single booby-trap), hence the printOnce suggestion.

Both stdout and stderr are bad candidates for this. Others (e.g.
separate file) have little sense as tripwires. Hence I'd say printOnce
is one of the few sane alternatives.
