Well that unsticks the test, so now it fails in an ordinary way, so +1
for doing that. I must say that --no-loop seems a little ill-designed.
Effectively we have to choose between zero loops and infinite loops. 
But that seems to be a matter of ancient (or at least medieval) history.

I will see if a more modern zlib helps matters.
