init quiescence after all templates are rendered
init quiescence after all templates are rendered

Hold off on initializing wait/quiescence until all templates have been
rendered once. This fixes an issue with -exec firing before the template
has been rendered when wait/quiescence is set, and it would also make
sure templates are rendered for once (if that wasn't already fixed
another way).

Fixes #1229
