ExclusiveCallbackHelper

class ExclusiveCallbackHelper<T>(coroutineScope: CoroutineScope, mutex: Mutex)

Helper for a re-occurring pattern where we need to suspend to wait for a result of an asynchronous call and during this wait no other call is allowed to be made.

The specified mutex defines the exclusivity of the instance.
