You cannot kill a thread. It's not a well defined operation. Most OSes do have the 
technical possibility to kill threads, but if you use them, you will not like the 
results. For a taste of small trouble, if a thread is holding a lock and you kill 
it, who's job is it to release the lock?

The best you can do is to ask the thread to gracefully shutdown itself. (I.e. by 
using global variable flags).

P.S. I did not implement the ss_thread stuff, I do not know what ss_thread_kill() 
does, but I recommend that you do not use it.

P.P.S. Programming using threads is complicated, I recommend that you read at least 
some literature on the topic before using threads. At the least you must understand 
the common pitfalls and mistakes. At the least, you must know about deadlocks, 
livelocks, race conditions and semaphore priority inversions.
