Okay, actually figured that out.
Turns out you need single quotes around the left-hand value as well.
So the loop should look more like this:
_loop :break_if => "'${/pending_documents}' == ''" do
# Some processing that slowly empties "pending_documents"
end
Otherwise the substitution yields " = ''" as a test, when the
intention is "'' == ''". >_<
