Frequent context switches

Not necessarily. The current thread may have as much right to run as the waiting thread, in which case continuing to run would also be correct behaviour. Only when a running thread itself waits or it has run out of allocated time is a thread switch needed for correctness.

Very interesting. However, I don't see what th_yield() has to do with anything. Unlocking a mutex that someone else is waiting for should automatically yield in a correct thread implementation.
