Part of concurrency control for stoptime updates. All updates should be performed on a snapshot before it is handed off to any searches. A single snapshot should be used for an entire search, and should remain unchanged for that duration to provide a consistent view not only of trips that have been boarded, but of relative arrival and departure times of other trips that have not necessarily been boarded. At this point, only one writing thread at a time is supported.
