Yes, and I know I am repeating myself, but if you use Dispatch/CobsDispatch like v0.4.1, you *can't* use it to dispatch async handlers. It only works with blocking functions, or spawning a whole task in the blocking function. I'll stop mentioning that

If you need async handlers (e.g. directly calling a non-task async function), you need to do it a bit more manually, like the v0.4.2 example.
