It's not possible to kill a thread. If you want a thread to have a
maximum time, the thread must check occasionally how long it has been
running and terminate if necessary.

Another programming language (Java) originally had the ability to kill
threads, but that was later deprecated because it caused problems due to
not knowing what the thread was doing when it was killed (it might have
been in the middle of updating something at the time, for example,
leaving the system in an inconsistent state).
