Description

Majority of blocks will be running some computations that do not fit into asycio processing. We have it only due to compatibility with model manager abstraction from inference.

That state creates lots of issues - for instance, while video processing, in threading environment Active Learning data collection was not working due to asyncio background tasks starvation.
