Has anyone benchmarked kotlin's SharedFlowImpl?
I'm seeing thread contention on a SharedFlow with several collectors, and a quick peek shows that that emitting & taking values all uses a single central lock per instance (.. and it's `this` which is an antipattern)

How does it work? SharedFlow is a hot flow. Actually, a Flow is a stream of data that can be computed asynchronously. There are two types of Flows,Cold Flow - Emits only when a collector is presentHot...

In this case it turned out that we'd sometimes batch post many flag updates to a SharedFlow with several collectors that were contending + triggering a GC.

It's like we saw the true face of the devil with EventBus, which blithefully reified the worst architecture patterns imaginable, and for the rest of our lives we get to hear people say things like, "SharedFlow is evil" and nod our heads silently in response, thinking "It could be a lot worse"

Yeah, that fits our investigation as well - more collectors, more lock contention on the internal SharedFlow buffer access.
