It depends if the thread was detached or not.

For a thread to terminate, it must
"reach the end of it's code block"
or
"return"

If it's not a detached thread, after you "return", you need to
join it, from the main thread, like
$worker_thread->join;


To force the thread to "return" when cancelled, you can
use a shared variable like $thread_die = 0, and when the
transfer is cancelled, set it to 1. Then in the thread code block,
check for it periodically, and if($thread_die == 1){ return}
A detached thread will then dissappear, and others need to
be joined.

There are many ways to do this, but you need to show your
thread code for more exact answers.
