Workflow seems to just halt (possible looping problem)

[Mike Pokraka]

Hi Adrian,

Shouldn't present any upgrade issues unless any tests fail. While loops
still work and are still supported, but you'll notice they are simply no
longer available as step types in the WF builder.
Based on this I wouldn't spend time on while problems and simply replace
them since every while can be built with until (now that's great English,
no?).

Cheers,
Mike
