Hi, is there a way to enforce only 1 subscriber per cold observable?
I'm looking at `subscriberOn(Schedulers.single())` but that obviously fails, when inside that chain somebody switches schedulers

What do you mean? Cold observables can have only 1 subscriber anyway. Consecutive subscriptions to the same cold observables result in new event streams.

You could argue that `ConnectableObservable` is also cold but it would be really strange to make an upstream connectable and allow to subscribe to it only once.

its a big hard to articulate. I want to allow only 1 subscriber running per all instances of a givem observable sync() : Single&lt;Unit&gt;

so if you subscribe sync() in 3 places, only 1st shoukd be running, others should wait
