... please always consider: can this loop become impossibly long? If
you are iterating over anything without set limits then the answer is
likely yes. Typically, nodes, files, users, terms, comments,
aggregator items, menu links are the things that some sites can easily
have millions of. Roles and vocabularies are an example which are very
unlikely to become unwieldy large.
