* Fixes an error where watching a compacted revision would return events, followed by an error. The watch is now immediately cancelled with an appropriate error, and the compact/current revision fields set. * Fixes an error where a high event rate could flood the GRPC stream with single-event watch responses. The event channel reader now merges all available events, and sends them in a single watch message. This was most frequently an issue on sqlite, where all inserts are done locally and immediately wake the polling goroutine to send the event without any opportunity for batching.
