That's a possibility, but I'm not convinced of even that as a real
sources which might easily be fed known data, such as writes to
/dev/random, are not flagged "estimate", so won't add to the "count"
if a user enables "collect" on, say, -t net, they can still leave
even those have sample times added as well as the known data,
which on a platform with cycle counters has a very strong chance
of unknown LS bits.
