Create a zero-value run.Group, and then add actors to it. Actors are
defined as a pair of functions: an execute function, which should
run synchronously; and an interrupt function, which, when invoked,
should cause the execute function to return. Finally, invoke Run,
which concurrently runs all of the actors, waits until the first actor
exits, invokes the interrupt functions, and finally returns control
to the caller only once all actors have returned. This general-purpose
API allows callers to model pretty much any runnable task, and achieve
well-defined lifecycle semantics for the group.
