Message:

Allow fast-switch to another runnable thread

When a thread is available that can be switched to immediately
without having to block, do so without a detour through CPU
scheduler context. The new thread will handle whatever cannot
be done while the previous context is active on a CPU, such as
requeuing the thread or deallocation.
