- Code cleanups around block graph modification
- Simplify drain
- coroutine_fn correctness fixes, including splitting generated
coroutine wrappers into co_wrapper (to be called only from
non-coroutine context) and co_wrapper_mixed (both coroutine and
non-coroutine context)
- Introduce a block graph rwlock
