Well, I have seen it hundreds of times on a dozen different Unices; it is very common. You don't always SEE the stuck process - sometimes the 'kill -9' causes the pid to become invisible to ps etc., and just occasionally it can continue to use CPU until the system is rebooted.

You're describing something caused by a buggy operating system. I have never seen any modern Unix exhibit any of the behaviours you describe. I have seen such things in the 1990's though.
