Multithreaded world causes deadlock in Godot #2
Description
Trying to step with B2Api.b2DefaultWorldDef_WithDotNetTpl() causes a deadlock in Godot C#. This is due to the engine providing it's own SynchronizationContext which forces continuations on the main thread.
Adding .ConfigureAwait(false) here seems sufficient
(As a sidenote, the Task.Factory.StartNew just above the mentioned line could also be replaced with a Task.Run, which would be a more "canonical" choice)

Thanks for the suggestion. I'll test this out a bit this weekend and change it if it turns out ok.

Your suggestion is now included as of 3.1.6.
Please note that there already is a 3.1.7, containing an update for the latest Box2D.
