| Nice side benefit of the new evaluator: it boots much faster, making it faster to iterate and test things, because it's only compiling virtual-program-level C code (Gpu, AprilTags); the kernel is statically compiled into a monolithic folk binary. (this feels like a reasonable tradeoff, since no one was messing with the kernel in practice anyway) | Nice side benefit of the new evaluator: it boots much faster, making it faster to iterate and test things, because it's only compiling virtual-program-level C code (Gpu, AprilTags); the kernel is statically compiled into a monolithic folk binary.

| + | * Fix memory leaks (it might end up better than old evaluator here too, since that is leaky anyway) | ||
| + | * Thread management so we can spin up new worker threads as needed to run Whens when current workers are asleep/ | ||

| + | There are still some high-level challenges from parallelizing the workqueue, stuff that we 'got for free' from having a single thread and converging to a fixed point. like, what order do you do operations in, how do you avoid wasted work, what does ' | ||
