Calls to `Backend.getOps()` can be quite expensive. In order to minimize the impact of these calls on the server, this change deduplicates concurrent calls with the same arguments, and makes only a single call, then invoking all the callbacks with the single result.

There was a problem hiding this comment.
agent.custom could in theory contain non-JSON-serializable objects, and also in practice could result in calls from different clients not being deduped.
We'll have to think on this a bit more - Alec suggested possibly moving it to sharedb-mongo instead
