Enable "realtime" use cases via render cache. Can we enable the render loop to proceed with last-cached render state, and allow a simulation loop (owns all Python objects and execution) to run on a fixed schedule? This is a formalization of the pattern that is pretty common: a timer causing simulation updates; the problem is that requires the simulation updates to be completed in a single frame. A separate loop would permit long simulation steps while frames are updated with running animations

Event Handler Complexity
Event handlers run on the main thread and block rendering

From john/McRogueFace/wiki/Input-and-Events.-

Providing consistent state is the challenge, but allowing event handlers to more thoroughly perform the simulation without losing frames is the reward.
