> ContinuousQueries have names that are unique across all the active ones. 
> However, when queries are rapidly restarted with same name, it causes races 
> conditions with the listener. A listener event from a stopped query can 
> arrive after the query has been restarted, leading to complexities in 
> monitoring infrastructure.
