This makes trace() much, much less useful. I'd say NAK, if this means
we're going to not come up with any useful behaviour. Why not define
something, then use it?

Nobody is going to say "look at the size of something and then do a
print() rather than a trace() if it's too small". Even looking at this
commit I'm not sure what "too small" is (one byte? four bytes?
sizeof(int)? sizeof(long)? A cacheline? what?) so I don't see how our
users can be expected to.
