Comment (by markjaquith):

 What I'd like for on-demand loading (say, in compare-two mode, or for fast
 scrubbers in single mode):

 A way to call `ensure` (a flag?) that says "I can wait for this". If that
 flag is set, requests are queued and then a debouncer coalesces them and
 passes them to `load` all together. It'll have to be based on
 `$.Deferred`, because `ensure` has to return a promise. Since we don't
 have a "collecting" debouncer, I was thinking about just maintaining a
 queue object with keys of diff IDs and values of a deferred object (they
 can all point to the same one). Then we can just have a dummy debouncer
 that just serves as a triggering device. When it goes off, we grab the
 queued ones, clear the queue, add them to the request, then iterate their
 deferreds, setting them to resolve when the `load` deferred does.
