This has been a real help! The ability to easily verify the behavior of certain pieces of code (especially mem management code) must have saved me hours of debugging.

Regarding the async code, sibling posts have addressed this. However, if you want to get a taste of how this is implemented in Moss look at src/sched/waker.rs, src/sched/mod.rs, src/sched/uspc_ret.rs. These files cover the majority of the executor implementation.
