Explore issues with asynchronous query execution

[lastmjs]

Render or stateChange functions could have issues because of the asynchronous nature of the execute query call. The state might change between when the subscription callback is called and the query is executed.

The problem is that when I run an update, I have no gaurantee that the render or stateChange function has been called even after awaiting the promise, since the render function is called asynchronously from somewhere in the asynchronous execute call...perhaps generators could help with this...

Or consider returning a promise and passing around the resolve function appropriately to resolve after the subscription is called
