Is

Dispatchers.Unconfined

equal to rx

Schedulers.trampoline()

? if so, why does my code not run blockingly if I replace all dispatcher references with the

Unconfined

one? That's what I used to do for testing in rx Is it not supposed to? To not impose any threading, i.e. run on native unit test thread? (Im aware of TestDispatcher, that works as expected)

A bit like but not exactly. It establishes its own unconfined loop at the top level to avoid unbounded stack growth.
