Hi,

The EFL is event-driven. This means that the application polls for data, and listens for events to interact with it.

If you move a blocking operation to a separate thread, it cannot block the event loop and keeps the user interface reactive.
For your information blocking the event loop and using long-running callbacks means the application cannot update its graphical user interface.
