Can't seem to reproduce with printf either.

It might be something fishy with my machine, with: 
	python -c "print('0'*4097)" | tr 0 1 | head -c 10
I get the broken pipe on my laptop, but on none of my other machines running arch...

(The sha256 sum of python, tr and head is also the same on every machine)
