This is a long one.

My problem: I'm having trouble backpressureing a function that is currently using an old pub/sub device on one of its events (that is to say: I have a producer that is running too fast for my consumer). I'm using guava's EventBus, which is old and very stateful. This works fine for many use cases, but in this particular backpressure case I've got deadlock for reasons I dont entirely understand if a subscriber calls runBlocking{} to attempt to block ImportantService when it fires a message.

EventBus is effectively depricated; it's really convienient for UI (read: giant stateful objects) but it's awful for any service trying to maintain referential transparency (read: using pure functions and composing message processing with things like flow.map)

At its core, I have this kind of object:

class ImportantService(..., private val eventPublisher: EventBus){
