Hello.

I have setup roughly like this

val completable = Completable.fromAction { /* do stuff */ }.subscribeOn(<http://Schedulers.io|Schedulers.io>())

// later in Applicaton.onCreate()
completable.observeOn(mainThread()).blockingAwait()

This blockingAwait completely hangs my app, no "stuff" gets done.
If i replace it with subscribe(), then "stuff" gets done, and everything's working.

Why is that?
How do I block my onCreate() until completable completes?
