1) If the thread is not exiting, then your function that you call on that
thread never completes, and you need to figure out why it doesn't.
Or 2) Or maybe it does complete, but without releasing a lock that it took.
You see, even if the thread didn't exit, that by itself would not cause a
hang when you try to create a new thread for the same function. In the
absence of locking in your code, you could create many many threads all
running the same function.
Or 3) You don't have explicit locking code of your own, but you're calling
code that does, and as in 1, the function you're calling never completes and
returns, thus holding a lock on some shared resource.
Impossible to say which without more information, but the solution is
absolutely NOT a "kill_thread" function.
