Awesome—thanks for everyone's answers; I think I'll go with delay/ force. What I'm a little worried about is the caching. After a calling of "alt" finishes, what happens to all those Delay objects and their cached values? Are they garbage-collected, or will they remain indefinitely? Should I worry?
