> We are experiencing OOM when Recon heap size is too small (1GB) and it looks
> like {{OMUpdateEventBatch#events}} is taking most of them.
> Goal:
> 1. Reduce new object creation when Recon is consuming batches OM events
> ({{consumeOMEvents}})
> 2. Improve {{OMUpdateEventBatch#filter}} to reduce memory usage. e.g. avoid
> generating a new list?
