When multiple members join/leave at the same time, we also emit 1 view per JOIN or LEAVE request. However, we could bundle multiple JOIN and LEAVE requests and only install 1 view. This would be enabled by collecting JOIN and LEAVE requests in a queue until

• N requests have queued up or
• M milliseconds have elapsed, whichever occurs first

Advantage: we can handle many JOIN/LEAVE requests at the same time, reducing time to emit views (VIEW_ACKs need to be sent fewer times)
