These uses aren't really doing a full yield. They are just giving up control

Unwind the stack on task failure
...
When a task fails, we will throw an exception, then catch it at the bottom of
the stack.
On Windows we don't do this yet because the exception doesn't propagate
correctly.
No cleanups yet.

Child tasks take a ref to their parents

This is so that when a child dies after the parent, it still holds a valid
pointer and can call supervisor->kill() safely.

Rewrite spawn yet again
...
The motivation here is that the bottom of each stack needs to contain a C++
try/catch block so that we can unwind. This is already the case for main, but
not spawned tasks.
