Possibly also virtual memory settings. Allocating gobs of memory with
a huge page file slows everything down without raising an error.

And since it's possible to have non-infinite but ridiculous-sized
iterators, I'd not bother putting too much effort into protecting
infinite iterators - although the "huge but not infinite" case is,
admittedly, rather rarer than either "reasonable-sized" or "actually
infinite".
