So use function pointers? You avoid a lot of overhead with
async_dispatch_f. Though I don't think that's going to get you realtime
constraints per below.

Well you've got timers that can be used for dispatch, and perhaps that
combined with the function pointer version of the interfaces can get you
close enough to realtime to do what you want?
