Thread.wait() is not a sleep method - it's what is sometimes called a 
join (as in Java) - it waits for a thread to finish execution. A thread 
cannot wait for itself to finish, hence the error.

We have a static Thread.yield() method and I don't know why there's no 
Thread.sleep(). It would be nice to have as a cross-platform solution.
