These all look reasonable to me. The size of the test case in the final
one is presumably arbitrary and just copied from t7004. I don't know if
it's worth trying to shrink it. It could shorten a rather expensive
test. OTOH, if we shorten it too much then we might get a false pass
(e.g., if the algorithm remains recursive but has a smaller stack

Now comes the hard part: rewriting the C code. :)
