    This assumption is that you control the lifetime of the thread, it is 
not detached, and you are responsible for joining the thread. In that case, 
pthread_kill is perfectly fine. If those assumptions don't hold, you have to 
do it some other way.

    Someone must have either been really confused or misread "thread" as 
"process".
