Race condition in DefferedResolutionOfBindings
There is a potential race condition in DefferedResolutionOfBindings
There are 2 calls to {{.Target}} per loop - those won’t be inlined so if you could do the lookup once you can cut the locks taken in half. Also not re-checking the result of {{.Target}} on line [4464|https://github.com/Unity-Technologies/InputSystem/blob/ab1b38a7b88a23a72fa519f66ed2fd345d85b373/Packages/com.unity.inputsystem/InputSystem/Actions/InputActionState.cs#L4454] is a race condition - a GC could occur between that line the check on [4444|https://github.com/Unity-Technologies/InputSystem/blob/ab1b38a7b88a23a72fa519f66ed2fd345d85b373/Packages/com.unity.inputsystem/InputSystem/Actions/InputActionState.cs#L4444].
